Slideshow Module Inaccessible in Lightroom 4.3

Since updating to Lightroom 4.3, I cannot access the Slideshow module. Each time I try, I receive the following message:
"An error occurred when attempting to change modules."
I have researched the problem and been offered suggestions to solve the problem. I have followed instructions to resolve the issue including:
replacing the preferences file (com.adobe.Lightroom[VERSION#].plist) and
deleting my user created slideshow templates
The problem still persists. Does anyone know of a solution beyond what’s stated here?

I am running OS 10.8.2 with LR 4.3 and I discovered this problem just the other day. I have reinstalled LR 4.3, temporarily moved all homemade slideshow presets, moved all preferences (as if they were deleted) and the problem persisted. So I tried disconnecting my second monitor (I have a 27" iMac with my second monitor being the 30" Cinema Display.) I got out of lightroom and restarted with the Cinema Display disconnected and the slideshow module worked just fine. I quit Lightroom again and reconnected my monitor and restarted the program and the slideshow module did not work. So for my situation and testing, the problem with the slideshow module exists while having the second monitor connected.

Lightroom 4 crashes when trying to open the slideshow module. I spent over three hours with both Adobe and Apple tech support and we know it is a permission issue but have not been able to get it solved. It started with the last upgrade to 10.8

Back up all data.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
Step 1
If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.
Triple-click the following line to select it. Copy the selected text to the Clipboard (command-C):
{ sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -Rh $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2> /dev/null
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2 (optional)
The first step should give you usable permissions in your home folder. This step will restore special attributes set by OS X on some user folders to protect them from unintended deletion or renaming. You can skip this step if you don't consider that protection to be necessary.
Boot into Recovery by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open.
In the Terminal window, type this:
resetpassword
That's one word, all lower case, with no spaces. Then press return. A Reset Password window will open. You’re not going to reset a password.
Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
 ▹ Restart
from the menu bar.

Running Lightroom 6 on Windows machine (after having upgraded from LR5... While attempting to add or change music in the Slideshow module, LR unexpectedly quits. After several attempts at this, LR6 won't even launch properly...shows the splash screen but that's it. The program is buggy...need an update/revision quickly!!

If you're on Windows, check out a free program called Audacity--it's fantastic. With Audacity the process of converting a 48.000 kHz to 44.100 kHz is as simply as opening, changing the sample rate, and then exporting again, as an MP3.

Lightroom's Slideshow Module export quality issue

When I export a slide show, the resulting quality of the photos in the pdf is much below that of the photos I see in the Library module. There is a high degree of aliasing (jagged edges) and if I export the slide show at less than 100% quality or at a screen size smaller than my client's, the pixelization renders the slide show useless.
I am using a Mac with the latest OS with a 256mb video card, 2GB RAM, and plenty of harddrive space.
I have confirmed with two other experienced photographers that this is also happening with them.
I have resorted to using Fotomagico as a slideshow software vs. Lightroom for the results from Lightroom are too unprofessional to show my clients.

Pat,
I just checked my slideshow output and it looks good. I can only suggest [and you probably have tried all of these: 1] Make sure your photos look good to start, high res etc. 2] make sure you have the latest Adobe Acrobat Reader [8 I believe] 3] restart LR [I hesitate to even say this]
Beyond that I don't have much to offer.
Good luck
Mel

If your Lightroom 6 is crashing in the Slideshow module, check the SAMPLE RATE of your music track

After spending over 2 hours with an Adobe technician who had control over my Windows 7 machine, I've learned something that I don't think Adobe knows yet... I upgraded from LR 5.7 to LR 6 (not CC) and began having issues when I was working in the Slideshow module. When trying to add a music track, Lightroom would crash ("unexpectedly quit"). I couldn't for the life of me figure out why. I turned off the GPU since a fair amount of chatter on the forum related to that, but it didn't change anything.
So I finally waited patiently for the Adobe Chat line to finally get a tech to respond...and he was exceptionally detailed and methodical in his approach to diagnosing my issues. I could follow on my screen as he did a variety of things that indicated he understood what he was doing. Unfortunately he got to a point where he thought (as did I) that he had found the problem/solution...which he thought was related to the bit rate. He concluded that music with a Variable Bit Rate (VBR) as opposed to a Constant Bit Rate (CBR) was causing the problem. Also unfortunate was that this "discovery" was near the 2-1/2 hour mark and we did not apply the scientific method to property determine if we had narrowed down to cause/effect.
Based on my further analysis, he was close, but not right on. It isn't the BIT rate mode that is causing the crash, but rather the SAMPLE rate. Turns out that the vast majority of songs in my iTunes library have a sample rate of 44.100 kHz--and those work just fine. However, I have about 15 songs, mostly downloaded as free background music from the YouTube creation library, that have a sample rate of 48.000 kHz--every single one of those cause my LR6 to crash.
If you're having a problem with Lightroom crashing in the Slideshow module, check the SAMPLE RATE of your music track.

Jeannine,
If you follow the advice of the previous poster Julie Kmoch and then gradualy add presets back in one at a time you might be able to find the one that is causing the issue. I may be guessing, but I believe the issue has something to do with either an incompatible Preset setting (eg a older preset in newer version of LR) or a corrupt Preset.
Say you bought LR2 and imported a bunch of Presets from the internet, cuz 'Hey these effects are cool and I don't have to recreate the wheel', and then you upgraded to LR3 (not a clean install) and now one of the Presets that calls a certain slider setting or value that is different in LR3 doesn't work anymore. This might be why it throws the error, but again I am just speculating.
Location of LR Preset folder in Windows Vista/ Windows 7
C:/Users/<YourUserName>/AppData/Roaming/Adobe/Lightroom/Develop Presets
If you do not see the folder AppData, you may need to change the settings in Windows Explorer to 'Show Hidden Files and Folders'. To do that in Windows Vista/ Windows 7, open a Windows Explorer window, Click on Organize, then Foler and Search Options. Then click on the View tab and select the option button next to Show hidden files, folders and drives.
Hope this helps a bit,
Glenn

Why are Lightroom 4.1 Slideshow Module Export Video 720p and 1080p ending up as Interlaced Video?

In Lightroom 4.1 (Windows 7 64 bit) when I create a slideshow in the Slideshow Module, use Export Video 720p or 1080p, the properties of the export do not agree with the name of the preset suggesting a fundamental discrepancy in what is stated and what is.
The MediaInfo properties readout for this type of export is showing Scan Type = Interlaced and Scan Order = Top Field First. How is this possible for 720p and 1080p which are designations for progressive video (no Fields)? However, the readout will show the expected frame rates, 1280 x 720 or 1920 x 1080 for 720p and 1080p respectively.
I suspect that this is not a misread by MediaInfo since a Mac user shows the same "interlaced" & "upper field first" information using a Mac Video Specs application for the properties readout for the Slideshow Module Export Video 1080p.

The LR slideshow module has had problems since its initial introduction and the issues have not been fixed in LR4.1. There is also an issue of resample artifacts (jaggies) when using portrait orientaion images in a slideshow on Windows platforms.. See this thread:
http://forums.adobe.com/message/3793720#3793720
Here's an excerpt from the above thread link:
LR has at least three different implementation versions, concerning this LR Slideshow Module behavior:
                         Stroke Border           Portrait Images
Mac OS:            Causes softness         OK (no resample artifacts)
Windows Vista: No issues                    Resample artifacts (jaggies)
Windows 7:        Causes softness         Resample artifacts (jaggies)

How do i put multiple pictures on one slide in the slideshow module?

The lightroom slideshow module appears to only allow one picture or one video per screen. I would like to put everything within one folder (usually 4 pictures) on one screen. any way to do this? Does anyone know software that will do this if lightroom doesn't? Thank you!

You could do this with Photoshop or using just Lightroom you could "print" mulitiple pictures to a jpeg file and then import the jpeg for your slideshow. Look under Print Job near the bottom of the print screen and choose jpeg file for Print To.

Can't get to slideshow module in 1.3

I can't get to slideshow module in 1.3 "an error occurred when attempting to change modules".
I am running Leopard 10.5.1.
Can anyone help?
Dan

I am still hoping that someone else has had this problem and knows a fix.
I have called tech support and I have learned that the only way they know to fix this is for me to create a new user account. If I create a new catalogue in the new user account I can then use Lightroom and the slideshow.
Obviously the hassle of moving everything into a new user account is not something I relish and am still wondering if anyone else has any ideas.

Can't access SLIDESHOW module.

When attempting to access the SLIDESHOW module I get the error message "an error occurred when attempting to change modules. This occurrs when using either the main task bar at the very top of the page under "WINDOW" or the horizontal list of modules near the top right of the page.

This could be due to a corrupt Preference File. This file can go "funny" and is then responsible for all kinds of strange behavior of Lr. The remedy is replacing the Preference File.
BTW: Re-installing Lr does not replace the Pref. File since it is designed to "survive" upgrades.

Missing EXIF data when PRINTING jpeg using Print or Slideshow Module (LR2)

Folks,
Is there a way to have LR2 include EXIF information when you create a JPG via the Print or Slideshow Module? The EXIF data is present if I export via the Library Module.
However, if I "print" a jpeg either under the Slideshow or Print Module, most of the EXIF data particularly the camera info is missing.
Thanks for your help.
Jg

Thanks Bob. I believe I have tried that...when you print to jpeg you have option where to save and I save to same folder and then re-synchronize folder in lightroom. Then I try to synchronized metadata between the original file and the new jpeg but the camera and other exif does not transfer over. The title, caption and copyright does work but your basic info such as camera, ISO, lens, f stop and shutter speed are missing
Regards,
Paul

Problems changing to Slideshow module

I recently updated to Lightroom 4.3 for Mac. When I attempt to change to the Slideshow module, I get an error message that reads:
"An error occurred when attempting to change modules"
Once I've attempted to change, other issues ensue and I usually have to close Lightroom and reopen the program. Has anyone else had this problem or should I contact support for help with this one?

Slideshow module causes system to crash

Hi,
I have a strange problem with Lightroom on Win XP SP3. When using the Slideshow module, I can typically play the slideshow for a couple of shots and then the whole system crashes. Typically so that the screen just goes blank and the computer reboots. This occures in two different computers, and the only common thing in these are Windows XP SP3 and Matrox G550 (latest stable drivers). The error also occures with both LR 2.1 and 1.3. I haven't been able to reproduce this with any other applications on these computers.
Has anyone else seen this? Have you been able to fix it? The way the computer crashes would indicate that the problem is in a low level driver, but there must be something in Lightroom that trigggers this.
Regards,
Mike

Thanks for replying,
> Possible solution YES.
Well, not in my case. I can reproduce this reliably even if I render 1:1 previews for all photos right before going into Slideshow.
>Can you post a crash report from the control\admistrative tools\event viewer logs for that particular crash.
No. The system just dies and reboots. Nothig is written to the event log, nor are there any crashdumps generated. And this is the same on both computers.
> How much memory do you have?
4 GB on both. Tried both with and without the /3GB switch, same problem regardless of this setting.
(Btw, system one is Asus MB, Pentium 4 HT, Matrox G550 AGP, single DVI monitor. System 2 is Intel MB, Core 2 Duo, Matrox G550 on PCIe, double DVI+VGA monitors.)

Slideshow Module: Slideshow getting stuck, won't auto-advance

We use Lightroom 4.3 in our studio to show our work to clients. One of our slideshows is based on a smart collection of all 5-star rated images. Before a client comes in, we'll click on the smart collection to load the images, go to the Slideshow module and use a preset we've created that has our desired background color, fade time, etc. and hit "play".
Recently this particular combination is not working properly. After a random number of images, the slideshow simply stops advancing and appears to be "stuck". If I hit the right arrow key on the keyboard to advance to the next image, nothing happens. However, if I hit the right arrow key twice, skipping the next image and going to a second image, the slideshow will continue. It will then get stuck again after a few slides. The only thing that I can figure is that by hitting the arrow key twice, I'm skipping a "bad" image that doesn't want to load. I can't tell what image that might be. The images that are held up on the screen seem to be different each time, because we are playing the slides in a random order.
Is there a way that I can figure out if there are some kind of "problem" images that cause the slideshow to hang? Has anyone else had this problem? Or does anyone have a different theory (other than the "bad" image theory) of what might be going on here?
Updating from 4.2 to 4.3 did not solve the problem.
Optimizing the catalog did not solve the problem.
Using a different slideshow preset does not solve the problem.
Using a different set of images DOES prevent the problem from occurring, but of course, I need to show these images. (Ex: a different smart collection that doesn't contain all the same images.)
OS: Windows Vista
Images: combination of CR2 raw, PSD, and jpeg
No error message. Slideshow simply gets stuck.
No recent changes to computer or software that I am aware of.
I just had a thought. I am going to go play the slides NOT in random order and see if I can find any pattern. In the meantime, any help is greatly appreciated.

Okay, I answered my own question. My thought about unchecking "Random Order" and then playing the slides quickly showed me the problem files. There were a handful of files that had a black circle with an exclamation point in them. This circle was where the question mark normally goes if LR can't find a file. When I clicked on the exclamation point, it said LR could not access the file, or something like that. I simply changed the rating on those images from 5 stars down to 4, which effectively removed them from my smart collection without having to delete them from my catalog. At some point, I'll go back and figure out what the problem was with those files, but at least my slideshow is back up and running!
The funny thing is that I've been google searching this problem for weeks with no results. Then I finally post in the forum and while typing the question, I figure out my own answer. Go figure. But I thought I'd post this up in case someone else has this issue, because there's NOTHING about this anywhere else I could find. :-)

Problems accessing Music Files in Slideshow module in LR 2.6 and Windows 7 64 bit

     Just got new computer 64 bit Windows 7. Installed LR 2.6 and am having problem with slideshow and music. Never had this problem before with my XP computer. When I open up slideshow module and go to Playback window and check soundtrack and try to choose a music folder, I have a new problem. It opens up "Browse for Files & Folders" dialog box as usual, but it only lets me browse on my desktop or my User name on the C drive. My music is in my F drive where my data is stored. I've never had a problem accessing my music in my F drive in my XP computer, but this setup limits where I can browse to. Interesetingly, this works OK in LR 3 beta on this WIndows 7 PC where it opens up a dialog box "Choose a music file to play" which gives me access to all my drives. In summary, I can't access music files stored on a drive other than my C drive using LR 2.6 on a Windows 7 64 bit computer.
     I have attached a screen shot to compare the new Windows 7 Browse for Files & Folders dialog box to that in my XP computer.
     Would appreciate any suggestions.
Thanks,
Matthew Kraus

Thanks for the reply. I went through the process you suggested to change Ownership & grant permission to access files. When I get to the owner tab in Advanced Security Settings....I am already the current owner of this folder.
What do I do now?
Thanks,
Matthew Kraus
