Whenever I try to launch a PDF file from my university website (lecture notes) I get this error:

What's the problem?

Adobe Reader needs an update.

Its something with the plug-in, I guess as Riv said it needs an update.

I tried installing an update and just before it finishes installing I get an error.

The PC might need an administrator level to install, that's what I beleive it might be but that shudn't let u start the installation itself.

I would say, delete Adobe Reader manually, install RegCleaner, kick it out from the registry, restart, then install the new one. But do this after making sure you have administrator rights to the PC.

adobe reader sux ,,, u should try out foxit :yes:
