HI, I have been trying to open adobe reader but I can't. At each time I do so this error message appears: "Invalid plug in detected". I have the adobe 8.1.2 version and windows vista..
What am I supposed to do? I need to use adobe urgently!
Thanks

Well, try to re-install it first then try to open it again...

I did uninstall it then I reinstalled it but it didn't work..

Really? Hmm... did you restart your computer after installing the software? :confused:
