Cannot open PDF files in my Hotmail account since this week. Hotmail says it is due to Firefox.

Cannot open PDF files in Hotmail while using Firefox. Using Google Chrome there is no problem. I already have Adobe Reader installed on my PC.

Hi Zwann,
Have you looked at the [[Opening PDF files within Firefox]] Knowledge Base article? There is a lot of useful information in there. They actually list 2 different PDF plugins. I'd give both a try if you are having issues.
Hopefully this helps!

Help - "Acrobat is being used by another application and cannot open PDF files until the other application is closed."

Hello,
I searched this site and google for this error terminology and come up dry. I support a user who has been for years using Acrobat 5 (yes, I know...) to read files in a client DB program, as well as other PDF files on their PC. In the last week or so, they have started gatting this error "Acrobat is being used by another application and cannot open PDF files until the other application is closed." any time they attempt to open a PDF file attached to an email (via Outlook).
It is my understanding that they cannot upgrade to a newer version of Acrobat because of limitations of their client software, but had not previously had any issues viewing PDF notes from the DB, and PDF attachments in their email.
I have tried uninstalling and re-installing, as well as tried using Adobe Reader 7 & 9 in conjunction with Acrobat to try to get around this issue, but have not been successful.
Any ideas?
Thanks,
Jesse

I don't have an answer to your technical problem. The product I assume is Acrobat that you are talking about (based on the post title), Adobe is the company name. This is a good place to ask questions on Acrobat if folks can figure out what you are talking about. They will ask for the product version number (like AA9.3.3), operating system, and other applications if appropriate. Also, just what you are doing that generates the message.
As for Adobe, you are not likely to get an answer from them here in the user forum. You will be lucky if you can get an answer if you can contact them and not be on hold for more than an hour (sorry, this is why a lot of folks end up in the forum).
So, to help others try to answer your question, what are the products and versions involved? What OS? What are you doing when the message comes up.

Cannot open PDF files with Reader XI message appears Adobe Reader has stopped working

Cannot open PDF files with Reader XI message appears Adobe Reader has stopped working. A problem has caused the program to stop working

Which Operating system you are using?
Can you open Adobe Reader by itself? If so, try disabling Protected Mode [Edit | Preferences | Security (Enhanced)] and then try to open the file.

Cannot open pdf files with Firefox's built-in pdf viewer

This just started (I think) with Firefox 37.01. This is on Win7-X64. I cannot open pdf files with the Firefox built-in pdf viewer. If I click on the file or try to open it from within Firefox, it brings up a "opening filename.pdf" message. If I select the "Open with" radio button as 'Firefox (default),' it just keeps looping on this process; it never opens. In Tools => Options => Applications, Portable Document Format (PDF) is indicated as 'Preview in Firefox.' I've never had any other PDF viewer installed on this computer. I've tried disabling all plug-ins and extensions, but it still doesn't work. I searched for solutions but haven't found any for this specific issue.
Thanks for the help.

Hello,
Have you tried, to start Firefox in safemode you can do so by following these steps
'''If Firefox is open,''' you can restart in Firefox Safe Mode from the Help menu:
* Click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
'''If Firefox is not running,''' you can start Firefox in Safe Mode as follows:
* On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac: Hold the '''option''' key while starting Firefox.
* On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' <br>(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".
;[[Image:SafeMode-Fx35]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
When you figure out what's causing your issues, please let us know. It might help others with the same problem.

Cannot open pdf files on my web site

i cannot open pdf files i uploaded to my web site. error message indicated i need to upgrade adobe reader. did that, still doesn't work.

What is the exact wording of the error? Apparently you got the PDFs from someplace else since you are using Reader. The major issue when uploading PDFs to a web site is to be sure you used a binary upload. PDF files are binary files and not ASCII files. I suspect that is the issue.

Hello. My safari (and i keep it updated) cannot open PDF files. Should i install Adobe Reader and which version????? I have Mac Book Pro running OS 10.9

My safari (and i keep it updated) cannot open PDF files.Should i install Adobe Reader and which version????/ I have Mac Book Pro running OS 10.9
Please help me!!!!

Back up all data.
If Adobe Reader or Acrobat is installed, there should be a setting in its preferences 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. Otherwise do as follows.
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, and test.
The "Silverlight" web plugin distributed by Microsoft can also interfere with PDF display in Safari, so you may need to remove it as well, if it's present. The same goes for a plugin called "iGetter," and perhaps others — I don't have a complete list.
If you still have the issue, repeat 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 again.

Hi Emily,
It seems to be windows profile related issue could you please try to delete the user preferences under the registries for which you are getting the issue for the particular users.
Note: The following resolution involves editing the registry. Using the Registry Editor incorrectly can cause serious problems that may require you to reinstall the Microsoft Windows operating system. Use the Registry Editor at your own risk. It is strongly recommended that you make a backup copy of the registry files before you edit the registry.For information on how to edit the registry key, view the 'Changing Keys and Values' online Help topic in the Registry Editor (Regedit.exe).
1. Go to start programs->run->RegEdit.
2. Then go to HKEY_CURRENT_USER< Software< BusinessObjects<Suite 11.5<Business Objects.
3. Select the user preferences and delete the same.
Regards,
Sarbhjeet Kaur

Hi Emily,
Following solution might help you to resolve the issue.
1.You create your Deski report.
2.Save as the report (with or without 'Save for all users'- makes little difference at his stage).
3.Export the document to the repository.
4.Save as the report once again with the option 'Save for all users'(overwrite the copy that already exists on the local machine).
5.Log into Info view and delete the report.
6.Log back into Desktop Intelligence and try to open the report.

Cannot open PDF files - generated response says I have to accept Licence Agreement. How?

Cannot open PDF files. Message generated says "Before viewing PDF documents in this browser you must launch Adobe Reader and accept the End User Licence Agreement, then Quit and relaunch the browser." Surely I must have accepted the Licence Agreement at the time of installation and am unable to "launch" Adobe reader. Anyone else had this issue please?

For Chrome I went went into the plugins: chrome://plugins/
The "Chrome PDF Viewer" was disabled. I reenabled it and it allowed me to view the PDFs again.

I cannot open pdf files from one supplier when using Adobe Reader but I can using another Viewer

I cannot open pdf files from one supplier when using Adobe Reader but I can open it if using Google PDF viewer or another viewer. The Adobe reader gives the error "There was an error opening this document. The file is damaged and could not be repaired" when I try to open the file. The version of Adobe Reader is 10.1.7, however I have tried other versions and they all fail the same way. I have tested on a number of different PC's in different networks and all fail using Adobe Reader but work using alternate viewer. Also the PC's will open a PDF from any other source.

Newer Reader versions are more strict than older versions (and other PDF viewers). If certain minimum requirements are not met, Reader will tell you that the PDF is damaged. This can happen when a document was created with software that does not adhere to PDF standards, or when the file was damaged during a download or email transmission.
You should contact the creator of these PDFs.

I cannot open pdf files in safari. It tells me first character is invalid. I have deleted plug-ins and reinstalled program. HELP

HI..
If you are using Adobe Reader ...
Try uninstalling the current copy of Adobe Reader first.
Best to use a utility to do this to make sure all the associated files are removed as well > Download AppCleaner for Mac - Uninstall your apps easily. MacUpdate.com
Then reinstall > http://get.adobe.com/reader/
Quit then relaunch Safari to test.

After activating "Click-to-play" plug-ins, I cannot open pdf files.

In the latest release of Firefox, information about how to prevent plug-ins from loading automatically was in the release notes. I activated this in about:config. (Click-to-play).
After that, I cannot open pdf files! When I click on a link all I get is an empty window. Reloading page don't help.
What I can do, is to click on the button next to the awesome bar and set that plug-ins will always load automatically for this page. Then the pdf file loads.
Another work around is to copy the link and paste it in IE.
Is this a bug with "click-to-play"?

Thanks cor-el. I have read the various bug reports and it is indeed the same. Has been known for a while...
Anyway, I find no mention of the work-around: "Click on the button next to the awesome bar and set that plug-ins will always load automatically for this page."
I don't know if there is a place to give that feedback.
