Cannot open jpg files in Preview? Error message "may be damaged or use a file format that preview does not recognize".

For some reason I cannot open jpg files from a co-worker who previosuly sent files without any problems. I just bought a MacBook Air with OS X Lion & Preview won't open the files. She sent the same files to another co-worker who opened without any issues? Help! Anyone have any suggestions after having the same or similar problem?

I don't have an answer as to why Preview doesn't want to cooperate, but if you only need to view the jpeg's and do nothing else to them, you can use two FREE applications that come already pre-installed on your Mac... Those are iPhoto and Safari. Just drag and drop over the application icon.
You can also find several FREE photo viewers in the APP STORE.

You cannot run Photoshop CS on a new Intel-based Mac running OS X Mavericks. CS is far too old.
You'll have to buy Photoshop CS6 or Photoshop Elements 12. Or subscribe to CC.

Cannot open Photoshop Elements. Receive error message 400 (Photoshop services are currently unavailable. Please try again later (I have) or check your network connections (they are OK). Error 400.

Photoshop.com is no longer available. The service transferred to Revel.
Ignore the sign-in altogether.
You may need to turn off Sync in Organizer prefs if you have it activated.

After updating os to 10.9.1can't open pdf files. I get a message saying It may be damaged or use a file format that Preview doesn't recognise. I can still read older saved files but no new ones arriving by email. Any help would be appreciated.

After updating os to OSX 10.9.1 I can't open any new pdf files. I get a message saying It may be damaged or use a file format that Preview doesn’t recognise. I can still read older saved files but no new ones arriving by email. Also can't attach a pdf to an email to send out. Any help would be appreciated.

Back up all data before making any changes. Please take each of the following steps until the problem is resolved.
Step 1
If Adobe Reader or Acrobat is installed, and the problem is just that you can't print PDF's displayed in Safari, you may be able to print by moving the cursor to the the bottom edge of the page, somewhere near the middle. A black toolbar may appear under the cursor. Click the printer icon.
Step 2
There should be a setting in its preferences of the Adobe application such as Display PDF in Browser. I don't use those applications myself, so I can't be more precise. Deselect that setting, if it's selected.
Step 3
If you get a message such as ""Adobe Reader blocked for this website," then from the Safari menu bar, select
Safari ▹ Preferences... ▹ Security
and check the box marked
Allow Plug-ins
Then click
Manage Website Settings...
and make any required changes to the security settings for the Adobe PDF plugin.
Step 4
Triple-click anywhere in the line of text below on this page to select it, the copy the selected text to the Clipboard by pressing the key combination command-C:
/Library/Internet Plug-ins
In the Finder, select
Go ▹ Go to Folder
from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens (command-V), then press return.
From the folder that opens, move to the Trash any items that have "Adobe" or “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari.
Step 5
The "Silverlight" web plugin distributed by Microsoft can interfere with PDF display in Safari, so you may need to remove it, if it's present. The same goes for a plugin called "iGetter," and perhaps others — I don't have a complete list. Don't remove Silverlight if you use the "Netflix" video-streaming service.
Step 6
Do as in Step 4 with this line:
~/Library/Internet Plug-ins
If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari.

"It may be damaged or use a file format that Preview doesn't recognize."

I have read through all the discussions and I can never seem to find a solution or answer to this that is working for me.
Currently in Spain on vacation, loaded all my photo's into iPhoto to clear my camera, like an idiot I deleted them from my memory card cause I've never had an issue with my Mac.
First I was getting a "no room on Home" message, then I re-open iPhoto and everything is gone, even historical pictures. I tried to rebuild, doesn't work.
I can see some of the photo's on my hard drive still and can open them in Preview, but others when I try I get this "It may be damaged or use a file format that Preview doesn’t recognize."
I'm still in Spain, wondering if I should re-take really important photo's or chance that this can be fixed by someone who knows what they are doing when I get home.
Dear heaven THANK YOU if you can help me.

If I'm reading this corretly, capacity is 249.72 GB and 165.3 GB is avaliable.
The home message has happened before, however the IT at work managed to fix it, until now.
Thanks again/in advance.

Hi. During the process of updating my ipad to IOS 6 utilizing iTunes, I received the error #1602. I tried the update procedure again, this time itunes does not recognize the devise. The pad is displaying USB connecter to iTunes. Can anyone recomend a fix?
Thank you

There is only one fix now. The message on the screen means that you have to restore the iOS software on the iPad now. Read the part at the very end about using recovery mode.
iTunes: Restoring iOS software - Support - Apple
About the error code.....
Error 1600, 1601, 1602
Follow the steps listed above for Error 1604. This error may also be resolved by disabling, deactivating, or uninstalling third-party security, antivirus, and firewall software. See steps in this article for details on troubleshooting security software.
If needed.....
Additional Information
If your device is continually restarting, not responding, or showing the Apple logo with no progress bar or a stopped progress bar, place the device into recovery mode and try restoring again.

TS3276 Well it happened again. Why does my apple me account stop sending mail for no apparent reason. One minute it is working find and 10 seconds latter you get error messages that it does not recognize your password. I am really fed up with the mail sof

Things were going well. Mail was working fine and then the following error message appears out of nowhere. I had not changed any settings. From that point on all efforts to send mail failed, and the error message appeared even thought I used the password to log back in after I quit. Now, an hour after the problem started it takes my password (on the second try after the error message appears) once and sends a test message. Then, one minute later it gives the error message again and refuses to send anything. Why is mail so inconsistent? What can I do in the future to address the problem?
Error message reads "The SMTP server "xxxxx" rejected the password for user "xxx" Please re-enter your password or cancel.
When mail does work again. Should I click the remember this password in keychain or am I just asking for more trouble?
I'm writing this using my IMac computer in a different room. The error also occurs on my powerbook running my new MacBook Pro 12 inch.
Fed up Mac user.

I"m no expert but this used to happen to me all the time (stop downloading, asking for my password, nothing downloading, walking away- 24 hours or more later, all is fine, only to later start all over again)
Well, i gave up for a long time and stopped using that account with mac mail and only accessed it online..recently went and changed the pop3 to only pop and now it works beautifully and seamlessly. Don't ask me why or how, but it does so thought I'd share.

Error: This application required an Xtra (ActiveX...) that either does not exist or failed

Hi All,
im having trouble few days now , i hope someone can give me a lead here.
i have a director mx file written in arabic, i open it in Director 11.5, the file behave strangely, very slow publishing process, very slow access to the xtra list.
after publishing (shockwave and html), i open the html, the preloaded start to run but i can see its not reaching 100%, after a while i get the error massage:
"This application required an Xtra (ActiveX...) that either does not exist or failed..." and firebox or IE crashes.
In the movie extra list (Modify menu) i can see all extras, and all have "download if needed", but in ActiveX the "download if needed" grays out. i have no idea why
things i try with no success:
uninstall and reinstall shockwave player
check the same file in another machine
exclude and include xtras in Publish Settings > Files
add activex.x32 from other places
Hope for good news
Win Xp sp3
Thanks
Shay

Because AX controls aren't SW-safe. You will have to redesign your file to remove the ActiveX control if you want it to run in a browser.

Ok, so this was done by Apple by purpose?
To clarify slightly what others have said, Apple licences the grey system discs that come with a Mac for use only with that specific Mac, not for use with any other Mac, even one of exactly the same model. So using them with any other Mac violates the terms of the license & should be avoided. The installer on the grey discs enforces this in part by checking the model of the Mac when it is run & refusing to install anything if the Mac is not the correct model. It displays a warning message that the disc cannot be used with that Mac & the only available option is to quit the installer.
Beyond that, while the grey discs may in fact include & install drivers for the hardware in other, older Mac models, they cannot include ones for Macs using hardware newer than the release date of the Mac they came with. In this case, the other Mac can't even start up from the installer disc & it freezes with a kernel panic before it can run the installer. This seems to be what happened here.

I cannot open firefox. i receive an error message instead: " your firefox profile cannot be loaded. It is missing or inaccessible" help

<blockquote>Locking duplicate thread.<br>
Please continue here: [[/questions/947572]]</blockquote>
after I received the error message, i uninstalled and then re-installed mozilla firefox. my desktop now has a mozilla firefox icon and a separate folder entitled: old firefox data. i tried a solution posted at the site:

Hello poestirs3
press Windows key + R to open the Run box of windows Vista, then type '''%APPDATA%\Mozilla\Firefox''' (or copied from here) and click "'''OK'''" to quickly open the appropriate folder,
then find [http://kb.mozillazine.org/Profiles.ini_file profiles.ini file] (see the screenshot how possible looks like) and rename it (right-click on mouse and select rename) to profiles.iniOLD , then when you start firefox again, a new default profile folder will be created and only a single profile, the new "default", will be listed in the Profile Manager.
This new "default" profile doesn't contain any of the profile data or settings stored in your old "default" profile folder, which still exists but is no longer accessible from the Profile Manager.
Your existing Firefox user profile data, which includes bookmarks, passwords, cookies, preference settings and added extensions, will no longer appear in the new profile but you [http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox can transfer the data from the old profile folder to the new default profile folder].

Calendar in gmail now refuses to open and I get an error message saying the page isn't redirecting properly and that Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

The error message suggests that this problem can sometimes be caused by disabling or refusing to accept cookies, yet cookies are enabled.
I want to import my calendar from Outlook but I can't even open the exisiting calendar I have already set up in associaion with my gmail account

When using (web accessed) yahoo email, firefox does not recognize my jump drive on my computer (but i can see when in file manager). Driver issue? Help/links?

I'm using windows 8 and try to attach a file from my jump, but it is not recognized, although I can see it in file manager.

Additional info. After restarting firefox and my computer, I was finally able to get to recognize the device, but now when I upload the file, it says file error and does not properly attach it. Ideas?

Cannot Open project due to permission error message

I am unable to open any of my Cap 6 projects. I get a message that says I do not have permission to open, but I am the only one using the program. I have recently upgraded to Windows 7 and MicroSoft 2010.
Any help would be appreciated to find out where I can grant myself permission to view my own files.
Thanks

Greetings Lieve,
I am wondering if Kelli has a read permission problem with the projects rather than a problem with Captivate?
Kelli, try this...
Copy your Captivate project(s) from their current location to your desktop (not a recommended storage location but this is just a test).
#1. Were you able to copy your projects?
#2. Can you open them into Captivate now?
Also, Lieve was correct. Captivate run with admin rights in most cases.
