Looked in forums, no help.  I've uninstalled, re-installed application twice, also repaired it.  No help.

Acrobat 9 Pro, Win 7 (64bit), Norton security.

Ok...I installed Malwarebytes Anti Malware Corp, removed the viruses I found. Since this did not take care of the problem, I then went to the "more tools" section and installed the "Anti-rootkit" tool. Followed the instructions and finally removed all the malware found. I then rebooted the machine and viola! I am now able to open my PDF files.

Perhaps you should give us verbatim what error message you are getting when launching Acrobat.

I assume you get this message when trying to run it. I would suggest you update Acrobat (9.5.3) since the 64-bit system requires the updates. I think that is even true for just running it.

Hi,

Please delete all files inside the "C:\Program Files(x86)\Adobe\Acrobat 9.0\Acrobat" directory and then run Repair for Acrobat  from "Control Panel -> Add and Remove Programs".

Thanks.

To delete the files you will have to launch the command prompt with Administrator rights, for doing so you should go to Start->all programs->accessories" and now right click on the command prompt which appears in the list and click on "Run As Administrator".

You can also delete the files by manually going to  the above mentioned directory (i.e C -> Program Files(x86) -> Adobe -> Acrobat 9.0 -> Acrobat ) and now select all the files and delete. UAC dialog will be thrown to ask for the elevation, click yes on that. In this process some of the files may not be deleted but that is okay.

Now run repair for Acrobat from "Control Panel -> Add and Remove Programs".

Thanks.

I know, I'm replying to an old message but maybe someone could help me. I've the same issue but with Adobe Acrobat Standard 11. Should I delete all that is inside the Adobe 11.0\Acrobat directory, including the folders inside that directory?

 

The Adobe Acrobat software came pre-installed with the Dell PC, no media (CD) was included/enclosed. And I've tried to repair and/or add components but after it seems it's going to work, it just rolls back everything it tried to change/fix.
