Trouble installing Digital Photo Professional and other Canon software

Hello everyone,
I have been trying to install several software programs on a new iMac without any success. My machine is the 20" Intel Core 2 Duo running OS X 10.4.8. I am attempting to install Canon's Digital Photo Professional version 1.0 and the EOS Digital Solutions version 7.0 (original equipment with my 1D mkII - will upgrade after installation). During the installation of DPP the process will stop while "configuring installation". I then receive a message that "There were errors installing the software. Please try installing again."
When operating the Canon EOS Digital Installer on the Solutions disk I receive the message "Not authorized to write to this folder".
As I am attempting to install this software under the administrative account, the error message for the Solutions disk puzzles me.
Does anyone have any ideas about what the problem is or where to begin troubleshooting?
Thank you in advance for your help.
Kevin

You may need to download the latest version (2.2.2).
It runs fine on my iMac C2D. Version 2.2.2 is also Universal Binary.
The only hitch you may have is the upgrade checks for an installed version. I'm not sure if it will accept the CD as an upgrade.
Where did I download it from? That I'm not certain of! I did a long search on Google & finally ran across a Japanese Canon site that had it.
If you can't install to upgrade, try installing it on a PPC Mac, install the update, then drag & drop the installed file to your new Mac.

Canon Digital Photo Professional and EOS Utility not responding

Have been using both Canon DPP and EOS Utility since Dec 09 successfully. Installed Snow Leopard in Jan 2010, still worked fine. Installed Aperture 3 in August and now the Canon software keeps shutting down on me. I contacted Canon and they said it is Apples fault (since 10.6.4) andthat it is because I am running Snow Leopard.
How can this be when it worked for 4 months fine?
Is this an issue with Aperture not wnating any ohter editing software?
I have a Canon EOS 50D camera and was exporting through the Digital Photo Professional software.
thanks to anyone that can help.

Hi MztengaM!
Welcome to the Canon Forums, and thanks for your post. Canon USA does have a Flickr Group already established! It's called "Canon Imagination." While it does not focus solely on Digital Photo Professional, it is the one and only official Flickr Group for Canon USA. Feel free to join and contribute!

Digital Photo Professional and Aspect Ratio on DPP Version 3.13.51 (3.13.51.0) OS X version 10.8.5

I recently up graded to DPP Version 3.13.51 (3.13.51.0) and it seems have lost the capability when cropping using the trimming tool to convert the cropped images to their cropped aspect ratio.
Shoot events with two cameras 6D and 50D. Always shoot RAW. At the end of an event may have as many as 1000 images to edit and convert to small sized JPGs for display on WEB. I bring in the RAW, select the RAW images to be converted, then from the Collection TAB edit the RAW. Editing may include cropping a 3:2 image to 4:3 or 5:4 or 2:3 or 3:4 or 4:5 or Custom. Once I have completed the editing and cropping I apply the BATCH Process to convert the RAW images to JPG and resize and rename. Here is where the issue appears. Before upgrading to DPP 3:13 I would use the following conversion selections :
File Format Exif- JPEG
Image Quality 10 Embedded ICC Profile
Resize (in Resize I would always select )
900 pixel Width and 600 pixel height with Lock Aspect Ratio
Then would name the file
With those parameters the converted and saved images would convert to the proper sizes with proper Aspect Ration as Cropped and Trimmed. I would always line up the images so that the 3:2 ratio would show in the selection window (5472 x3648) then I would enter the new desired size (900 x 600) . The 3:2 images would convert to 900 x 600 and the images cropped to 5:4 Aspect Ratio would convert for example to 642 x 514 (the proper ratio for 5:4).
With the new version 3:13 the image cropped to 5:4 also is converted to 900 x 600 rather than the desired 642 x 514.
This is a real conundrum for my workflow. It works the same way even if I uncheck the Lock Ratio Option on the Resize command options.
How can I fix this? If uninstalling and reverting back to the older version of DPP is my only solution, what are proper steps for uninstall and reinstall of older version and maintain data structure.
I have Lightroom but have never been able to get a workflow as efficient as the DPP flow for converting hundreds of RAW to small cropped JPGs.
Thanks for your help.
Don
Solved!
Go to Solution.

I don't use DPP enough to help you with your issue. But Lightroom is really great program for batch processing. It is much much better than DPP, so you may want to look at it again since you arealdy have it.

Digital Photo Professional and .WAV Files

Is there a way to get DPP to display and play .wav files created with a 1 Series camera?

Rddelliot,
Unfortunately, DPP does not support WAV files, so it is not possible to display them or play them back in DPP.

Installing 10.5.1 and other Apple Software makes my Boot Drive Invisible !

Hi There,
I need help,
after installing the leopard Update 10.5.1 my System booted just fine but after logging in I noticed that my boot drive WAS NOT visible in the finder sidebar or desktop...
I opened Tinkertool System and looked at my hard drive. And it had mysteriously been set to "INVISIBLE" in the HFS and Finder Attibutes.... After setting it to "Visible" again I could see it in the finder....
Can someone PLEASE explain this.....
Leopard is great but one has to do a BUNCH Of trouble shooting to get it to purr

The installation instructions state "installed" not "active'
I don't believe Apple makes Tinkertool. You should have uninstalled it before upgrading.
I believe Tinkertool qualifies as a system modification.
The install instructions cleary say
Important: Read before installing
You may experience unexpected results if you have third-party system software modifications installed, or if you've modified the operating system through other means. (This does not apply to normal application software installation.)

Lenses not listed in the Lens Optimizer in Digital Photo Professional

As the topic title states my lenses are not listed in the Digital Lens Optimizer. I've placed the CD in the tray, and yet the program says it's connecting to the server, and when done, they are not found in the list. The lenses are:
EF-S 18-55mm f/3.5-5.6 IS II
EF-S 55-250mm f/4-5.6 IS II
Why are they not listed? How do I get them?
DPP version 3.13.0.1
EOS 70D / EOS Rebel t4i / EF-S 18-55mm f3.5-5.6 IS II / EF-S 55-250mm f4-5.6 IS II / Sigma 17-50 f2.8/ Canon EF-S 60mm f2.8 macro/ Canon EF 100mm f2.8 macro/ Tamron 70-300mm / 430EX II Speedlite / Canon FS 300
Canon Pixma MG 3100 / Canon LiDE 2100
Adobe Lightroom 4, Canon DPP, Corel Paintshop Pro X4

Of the lenses I have, the following are not supported by DPP 4 (However, they are supported "in camera" with EOS Utility 3)
Canon EF 50mm f/1.8 II USM
Canon EF 20-35mm f/3.5-4.5 USM
Canon EF 24-85mm f/3.5-4.5 USM
Canon EF 28-90mm f/4-5.6 USM
Canon EF 28-105mm f/3.5-4.5 II USM
Canon EF 28-135mm f/3.5-5.6 IS USM
Canon EF 75-300mm f4.5-5.6 USM
I don't care if they are "old" lenses or not. Why have the correction profiles for "in camera" correction (when saving/converting to JPG) and not in DPP 4? They have the data, they could just port it over from the database used in EOS Utility 3.
These lens correction profiles bring new life to some of the old "film" lenses like the Canon EF 20-35mm f/3.5-4.5 USM lens. That lens has lots of distortion. However with in camera correction, it now produces good pictures.
I am not a professional photographer. I am a photography enthuisasts. I'll NEVER spend $1,000.00 or more for an "L" series lens (in fact I sold the Canon 24-105 f/4 L "kit lens that came with my EOS 5D. It was way too heavy, and the zoom on the low end was cramped (only 4mm movement between 24mm and 28mm). I like/use my Canon EF 28-105mm f/3.5-4.5 II USM and Canon EF 28-135mm f/3.5-5.6 IS USM better.
Maybe my mistake is that I am using a program call Digital Photo Professional and I am not a professional. I noticed that that software leans heavily and supports the "L" series lenses.

Hi,
The Canon 70d is a very nice camera that is quite new.
Will the DPP 4.1.xx software be available for it in the future?
Thanks,
Steve

This is the info, including the link to the Canon website.
Canon has released an updated version of its Digital Photo Professional (DPP) software, which now supports – in addition to its current range of full-frame DSLRs – the EOS-1D Mark IV, EOS 70D, EOS 7D Mark II, EOS 7D, EOS 5D Mark II, EOS 700D and EOS 100D…
Launched in September 2014, Digital Photo Professional 4 was Canon’s first sweeping change to its popular RAW processing software since its original launch. The latest version of DPP – version 4.1.50 – is a response to feedback from owners of older full-frame and APS-C cameras who are looking for the very latest RAW workflow solution.
Additionally, DPP 4.1.50 supports the recently launched EF100-400mm f/4.5-5.6L IS II USM and EF-S 24mm f/2.8 STM lenses, the profiles for which are now available for use with the Lens Correction function.
Commenting on the update, Mike Owen, European Professional Imaging Communications Manager, Professional Imaging Department, Canon Europe, said: “DPP 4.0 has proved incredibly popular with our customers and this latest update further extends its appeal to a wider range of users, such as those using the highly successful EOS 5D Mark II. Canon remains firmly committed to offering a complete range of products to photographers and increasingly its software solutions are playing a vital role in delivering the ultimate in image quality from capture to output.”
DPP 4.1.50: KEY FEATURES
Faster, real-time adjustments.
Improved RAW file workflow.
Better, more approachable user interfaces.
Compatible with 64-bit native environments.
Colour adjustments for specific colour gamuts.
Improved highlight recovery provides expanded tonality.
Improved shadow recovery function.
Support for movie playback.
Auto Lighting Optimizer can be applied to JPEG images.
Better integration with EOS Utility.
You can download DPP 4.1.50 now, free of charge, from Canon Europe’s support site here. Just click on your camera – EOS-1D X, EOS-1D C, EOS 5D Mark III, EOS 5D Mark II, EOS 6D, EOS-1D Mark IV, EOS 70D, EOS 7D Mark II, EOS 7D, EOS 700D and EOS 100D – and select DPP 4.1.50 from the software options to download.
I got it, and it seems to work. I haven't had a chance yet to see whether it fixes any of the bugs in the previous release or improves on the awkward user interface. But it does work on my 7D RAW files, which is what I badly wanted. That said, it still doesn't work on files from my wife's T2i; and since we do some photo shoots together, that remains an annoying inconvenience. I think they should just make V4 work on all .CR2 RAW files.
As of this morning, the new release is still not on the Canon USA Web site, nor is there any mention of it there.
If you haven't downloaded DPP V4 before, don't be blindsided by the fact that they make you enter the serial number of a qualifying camera. If you don't have that on your computer, you'll want to look it up ahead of time.
There's also a new release of Version 3 of EOS Utility. But it appears that the only addition is the aberration data for one or two recently released lenses.

How do I go about with Canon Digital Photo Professional installing?

When I bought my Canon 40D two years ago, I got a cd "Canon Digital Photo Professional 3.3."
I use that on my windows based computer for manipulation. Now..
I wish to install this software in my Mac Book Air. Since I have Aperture 2.1.4 on this MBA, Do I have to choose any particular directory for this Canon DPP install.
Will Canon DPP work along side the Aperture or work as a plug in for Aperture?

Hi snowshine,
when you launch the DPP installer it will create automatically a folder named Canon Utility in the Application folder...mine did so, I didn't changed the default settings.
After installing DPP from the CD be sure to go to the Canon website and install the upgrade, there are several available, along with Picture Style Editor and a new version of the EOS Utility.
DPP and Aperture are two distinct applications, they can live together, no problem...I have installed DPP and Aperture 2.1.4 on my powerbook G4, DPP and Aperture 3 on both iMac and macbookpro..and everything's fine.
DPP will not act as an Aperture plug-in...but you can set DPP to be the external editor for Aperture if you need so, you can set the external editor program by going in the Aperture Preferences.
Ciao!

Difficulty Installing Updates to Digital Photo Professional

I'm trying to install an update for DPP. I've downloaded the latest file from Canon, unzipped it and clicked the installer. I however get a message back that I don't have sufficient privileges to install and to log back on an an Adminstrator. I've checked and am logged on as an Adminstrator. Any thoughts as to why the difficult?

I didn't mean to imply that the camera model had any effect on the issue, but rather that Canon is possibly not offering the same version of DPP for all of its models. Knowing the model, anyone can look at the specific download page for it to see which version they're offering. If it's not the latest, try going to the SX1 IS download page and download the version I installed last night.
Edit: I just checked the 7D downloads and the same version is offered (3.12.41); here are details on the system requirements for it:
3. Target Applications (required for update)
Make sure that at least one of the following applications is installed.
- Digital Photo Professional
- RAW Image Task
If any of the above applications is not installed, prepare one of the following installation CD-ROMs.
- EOS DIGITAL Solution Disk v1 to v25.4
- DIGITAL CAMERA Solution Disk v2/32/32.1/38/38.1/38.2/39.1/53/54/71/72/73/74/96/97/99/100.1/101.1/122/123/124 /125/126/127
- Digital Photo Professional Disk v1 to v1.6

Lightroom 5.5 and Digital Photo Professional 4

My workflow includes processing my Canon 6D RAW files in LR exporting them in reduced size JPG format to a folder on my external drive and then opening up the images in Digital Photo Professional (versions 3 and 4) to review and tweak before submission.
I updated to LR5.5 and DPP4 simultaneously (stupid). Now when I follow the above work flow, the JPG files created in LR5.5 can not be read in DPP4 (or DPP3). I have called Canon, they are not aware of the issue and had no really good feedback. DPP4 can read all other previous LR JPGs created prior to the update to LR5.5.
I have uninstalled DPP3 and 4 and reinstalled DPP 4 with same results.
Anybody on the Lightroom end know of any possible explanation?
Thanks,
Don

The short answer is that Adobe changes something in LR and PS-ACR that puts the JPG header sections in a different order, and while this may be within the JPG standard, some programs including DPP don’t know how to handle this change, and won’t open the LR 5.5 JPGs.
The release notes for ACR 8.6 RC say Adobe has changed things to make JPGs readable by more applications. Presumably this will reverse whatever was changed, but there is no LR 5.6 RC so you’ll have to wait for LR 5.6 final, or put LR 5.4 back if you don’t have a camera that needs LR 5.5+.
Older versions of LR are available at the Adobe Updates page:

Mimicking Canon Digital Photo Professional Picture Styles

I use a Canon 400D and I would like to be able to use Lightroom in such a way so as to be able to mimic the Picture Styles that the Canon Digital Photo Professional software can produce.
The Canon Picture Styles include settings called Standard, Landscape, Portrait, Neutral, and Faithful. I am mostly interested in the colour rendition produced by each of these Picture Styles.
Does anyone have any presets or the like that will enable me to mimic these Picture Styles in Lightroom to at least some degree? The ones called Neutral and Faithful are of the most immediate interest to me.

It may be helpful to know what the Picture styles are doing to your images in the first place.
Standard takes the pictures with a "normal" colour balance,it increases contrast and saturation a little and increases sharpening to 3 on a scale of 0 to 7
Portrait takes the picture with a slight colour bias towards red to enhance the skin tone, it increases contrast and saturation but less so than standard, sharpness is set to 2
Landscape takes the pictures with an increase in the blues and green colours, contrast and saturation are increased more than in standard, sharpness is set to 4
Neutral does nothing much to the image with no increase in saturation, contrast or sharpness which is set to 0. the colours are handled in the same manner as Standard
Faithful is the same as neutral but the colours are based upon a white balance of approximately 5200K, it is designed to minic film in how it handles the colours. It too does not sharpen the image.
More details can be found at http://web.canon.jp/imaging/picturestyle/index.html
I know this does not answer your questions but it at least should start you in the right direction

IPhoto vs Canon's Digital Photo Professional for RAW

Greetings,
Quick question after not finding much while searching the forums:
I’m currently using a MBP C2D, 2.33/2G ram, all updated software. Just got a Canon Rebel XTi, finally putting aside my Canon 35mm (for now anyway).
Can someone offer feedback on iPhoto vs Canon's Digital Photo Professional for RAW editing for someone with limited experience with RAW editing?
I understand there are also other options out there but I'm trying to compare what is basically free/already provided, perhaps upgrading once I become more experienced with Digital/RAW editing.
Thanks in advance...
MBP C2D Mac OS X (10.4.8)

wdunn:
Welcome to the Apple Discussions. Nearly all, if not all, professionals use RAW in their shooting. There are a lot of advantages to that if you know what you're doing and need the extreme control over the image that pros usually do. I hang out in the iView MediaPro forum. Over there it's nearly all RAW users and I've learned a little of what they can do with fine tuning a photo. It is considerable. But for amateurs like us, jpgs are more than enough.
I've edited and saved a jpg file many times to see if I could detect the "degradation" and couldn't. If one was going to make a very, very large sized print then you might see something after a number of saves. Personally I use Photoshop for my editing and on "special" photos I create a psd file, duplicate the base layer and do my edits on the duplicate layer. That way I can easily compare to the original, and keep the resolution quality the same throughout. But, only on special projects.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application (requires Tiger), iPhoto dB file backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Do I need to convert RAW fles using Canon's Digital Photo Professional?

I want to create a "fake" HDR photo from a single RAW file using Photomatix Pro, which can open RAW files from my Canon S95 directly. But the finished HDR is almost unusable because of too much noise. So the only way out seems to first convert RAW images into Tiff format. Unfortunately, Canon's Digital Photo Professional for Mac produced errors whenever I want to batch process raw images.
Actually the Aperture 3 can read Canon's RAW images (.cr2) directly, and I can export 3 TIFF versions of different EVs to "cheat" the Photomatix into creating an HDR image. But I have doubts about how capable Aperture 3 is in converting Canon's proprietary RAW files as compare to Canon's own Digital Photo Professional. Could I simply use Aperture 3 exclusively for RAW conversion and forget about Digital Photo Professional?

While Wikipedia is a valuable resource, remember that it is not peer reviewed so the level of accuracy isn't always that dependable.
One of the reasons why Apple, Adobe, and others are always behind by several weeks to a few months when a new RAW profile comes out is that they are decoding it. Thousands upon thousands of people use Canon & Nikon RAW files every day and the large majority never use DPP or Nikon's equivalent.
I used to use DPP before Aperture came out and even with Aperture's initial problems, it blew the doors off DPP in workflow speed and consistency.
In my opinion, DPP only has relevance under two circumstances: 1. If you use customized Picture Styles and want to make your RAW file equivalent [somewhat irrelevant as you can create custom profiles for a camera in both Aperture & Lightroom which solve this problem - you do have to create them though by trial and error]; 2. If a new camera comes out and you must get it before it is supported by Aperture or Lightroom [Though, Adobe's DNG converter often allows you to skip over using DPP by converting your RAW files to DNG for use in Aperture or Lightroom]
Finally, the community support as well as tech support for DPP is dreadful - pretty much doesn't exist compared to that of Aperture & Lightroom.
Hope this helps!
Best,
CD
