Acrobat failed to load its Core DLL--can't open pdf files as a result

[Angie_C...@adobeforums.com]

I just installed Acrobat Reader 9 and I am getting this error message. I shut down the computer to no avail. I am not able to read any pdf files. Any help is appreciated.

I am having the exact same problem. I don't know what happened to my Acrobat. It has always worked perfectly. Then somehow it was corrupted and I have tried to update it, restore it or do what I can all to no avail.

Louise, I restored my pc to an earlier point and now I have version 8. Try restoring your computer to preinstallation date of version 9.

It works great!

I was wondering if either of you have the Quickbook PDF Printer? This has caused the error in the past with Reader 8.

I do not have the Quickbook PDF Printer.

I am facing the same problem with the fresh installation of Acrobat reader 8.1.3 . I am unable to uninstall the ver 8 or upgrade it to ver 9. Everytime I try to do so, I get the fatal error "The installation package could not be opened, please contact the application vendor". Please help , I am unable to open any pdf file.
I have a new machine with lots of software are installed in the last few days. therefore I cannot restore it to any previous day.

thanks in advance and hoping to get a positive from you soon.

Try doing the following to see if this helps:

go to: Start
Search all files and folders
Type: Adobe

If any results show up delete all of them and empty the recycle bin. Then go to Google and do a search on Adobe removal and follow the instructions.

After you remove everything restart the computer.

Let me know if this works and good luck!

Is anybody who is receiving this error message running CA Antivirus? Reason I ask is I found this article in a different blog:

"It turns out it was a conflict with CA antivirus and Adobe. It matters what order they are installed .
To fix I unistalled CA anti-virus> rebooted> Uninstalled Adobe Reader>downloaded Reader 8.0>installed Reader".

I haven't tried it yet, but was just wondering if there is a common amoungst us all like CA Antivirus?

You must uninstall it and restore your computer to earlier date when you had version 8.0. That's what I did and it worked for me.

Are you using Firefox? I got this error(adobe failed to load core dll) after installing Adobe 9 and believe that was the problem. There are instructions for installing Adobe 9 in Firefox. The link is on the intall Adobe Reader 9 page. I couldn't follow the directions exactly because they are probably for an older or different version of Firefox than I have but basically you have to tell Firefox to allow www.adobe.com to allow add-ons. I uninstalled Adobe, rebooted and followed the directions to allow add-ons and reinstalled. Ta-da! It works now!
