First - what version of Adobe Reader do you have?
And now it gets a little bit complicated. Adobe Reader can be a plugin to Internet Explorer, and it crashes when you try to open an online PDF document. That is not unknown; it happens sometimes.
But when you open the standalone Adobe Reader, it also crashes with a plugin error. This time it must be a plugin to Adobe Reader, not Internet Explorer.
Furthermore you write "the same plugin error window pops up" - so I can only assume that it is a Reader plugin that crashes, not the IE plugin.
What I would try in your situation:
- open Control Panel | Add/Remove Programs, and uninstall Adobe Reader;
- open Windows Explorer and navigate to C:\Program Files\Adobe\Reader 9.0\Reader and delete all plugin... folders;
- reinstall Adobe Reader from http://ardownload.adobe.com/pub/adobe/reader/win/9.x/9.3.3/enu/AdbeRdr933_en_US.exe
The path in the second line above could also be ...\Reader 8.0\... depending on your Reader version.
Thank you! That absolutely cleared it.
For posterity, I was using Reader 9.3.3 and the only plugin in the "plugins" folder in Windows Explorer was some program called "Babylon". When following your steps I left the old Reader (9) in Windows Explorer alone... I wasn't certain from the instructions if I was supposed to delete it after uninstalling it, so I just left it and deleted the "plugins" folder, as indicated.
I checked my ability to read a pdf using Adobe in Mozilla (3) and the newly re-uploaded Reader (9.3.3), and it worked fine.
Thank you again!
You're welcome - glad it worked. Yes, we have seen plugin errors associated with "Babylon" a lot recently.
