Hello,
I am experiencing an Adobe Reader 10.1 issue with computers running Windows 7 32 bit with IE9. When the user goes to a SharePoint page and tries to open a PDF we see the following error:
"There is a problem with Adobe Acrobat/Reader. If it is running, please exit and try again. (1:1)".
There is no other instance of Adobe Reader running. The user accounts that log in are domain user accounts and have user level security access. They can open PDF files that are stored locally on the hard drive but they cannot open any PDF that is listed on a SharePoint page and only see the error message stated above.
I have been looking at different forums. I have tried the suggested fixes but none of them have worked.
I have tried the following things but they did not work:
Repaired\Reinstalled Adobe Reader
Unchecked the "Display PDF in browser" setting
Made sure "Do not save encrypted pages to disk" was unchecked
Run the SharePoint page in compatability view
On one of the Windows 7 computers I created a local user account. Added it to the local Users group. Logged in and launched IE9 and navigated to the SharePoint page. I clicked on a PDF link and received the same error as stated above. I then moved this new local user account to the Power Users group and performed the same test with the same results. I moved this local user account to the Administrators group and now I am able to view PDF files within the IE9 browser. I tried this with other administrator accounts and all works fine. So it appears to be a security rights issue. I looked at the GPO's and did not notice anything that would cause this issue. Of course, I am not a AD guru so I might have missed something.
I have loosened security rights on several Adobe directories but that did not work.
I need to have domain users with user level security access to be able to view PDFs in the IE9 browser. Any help is greatly appreciated.
