I needed to download an important PDF but Firefox was telling me it couldn't launch Acrobat so I uninstalled and tried to reinstall the newest version, 9.3.3 and around 80% it gives me an error message saying:
Access is denied.
File: C:/Documents and Settings/[User Profile]/Local Settings/Application Data/NOS/nos00820//nos#.tmp
I've tried installing four times and each time the # is a different number, but when I look in the folder specified, there is no file in there with that number. There are other nos temp files with different numbers however. wtf?
