Adobe Acrobat Issue - Vista Ultimate


When i try to install Adobe Acrobat reader 8.1 it complains about nppdf32.dll in Mozilla Firefox folder. Also it says in the error that I don't have sufficient access.

I downloaded this dll and try to copy it into C:\program files\Mozilla Firefox folder/Plugins/ but it gives me issue of not SUFFICIENT PREVLIGES

You say Acrobat Reader 8.1... Have you tried the latest version which is 8.1.1? Or is that the one you mean?
