Adobe Reader 8.1.3 gives 'Invalid plugin detected" error then shuts down

Medium Priority
Last Modified: 2012-06-27
Couple of my users are experiencing this. When they open Reader, it gives them "Invalid plugin detected" error message. When you click ok, another window pops up saying

"The instruction at "0x2d830cbc" reference memory at "0x00000008". The memory could not be "read". Click on OK to terminate the program".
Then Reader shuts down.

This has happened on a laptop and desktop. Same result whether opening a PDF directly or through one of the other apps (Outlook, IE, DM) Even happens when opening just Reader without a PDF. I've tried reinstalling Reader, repair function within Reader, and reinstalling Office and DM. All worked for about a day and then the problem came back. Everyone in the office is using the same set of software, but this is only happening for these 2 users so far. We can't install Reader 9 because our current version of DM is not compatible.

Sounds like you have a dodgey plug-in.

1: Locate Reader folder...  usually in C:\Program Files\Adobe\Reader 8.0\Reader
2: In the Reader folder, find the "plug_ins" folder and rename it.
3: Start Reader and user the "Repair Adobe Reader Installation" in the Help menu.
4: Once repair is complete check back to the Reader Folder and a new Plug_ins folder should have been generated.
5: Delete the old renamed folder.

Hope this helps.

Ask the Experts


I've uninstalled and reinstalled Reader, waiting to see if users report issue again. Probably won't hear back from them until Tue 2/16 since Monday is a holiday. If error comes back, I will attempt repair using this method.


Finally was able to test this on both users. Been monitoring their computers for a few days, no issues. Thank you!
