Acrobat 8 pro freezes

I've been running Acrobat 8 pro on a 64bit machine under Windows 2012 R2 for some time. It worked fine until a few days ago. Now it freezes after a few seconds, usually less than 30 seconds, whenever I open  it with or without a file. Also trying to print to the Adobe printer just results in a document stuck in the queue. I have tried the following with no luck:
starting in safe mode
moving all the API's
repairing the install
checking for temporary files--there are none
running sfc /scannow
trying to turn off protected mode-cannot find any such switch
updating graphics drivers

So I'm open to suggestiions.

See if you can update Adobe. Some people have made it work.

Adobe Acrobat 8 failed on my Vista 64-bit machine some years back. Adobe said it was an Acrobat 8 issue and said Acrobat 9 would fix the problem. They gave me a free copy and Version 9 worked very well.

Acrobat 8 and 9 are long dead. Adobe V11 and V2015 (DC) work very well in 64-bit machines and you probably should upgrade.

Ihave seen many people state that upgrading to ver 9 did nothing to fix this problem.  Has anybody provided an explanation of this issue and why ver 9 or later should work?

I have not had any issue with V9 on 64-bit but like V8, it is dead. Try a much newer version

upgrade or uninstall and install?

Uninstall all old Acrobat and install the newer version. If you can restart the server in between please do.

OK, Will try that. Thanks for the advice.

That did the trick. Although AcrobatXI Pro works well, I still don't know why 8 worked and then didn't.

@PCGenieLA  - Thanks for the update. I am not sure about Acrobat 8 because it is so old. But I used Acrobat XI until recently, and it worked very well. So also does Acrobat V2015.
