I have software installs failing because files are needed to be added into the C:\Windows folder. Once I discovered the problem, I tried a manual fix (logged on as an administrator account) by inserting a new file into the Windows folder. I can't do it. I may the last person in the world to figure out that an administrator cannot insert a file into the Windows folder. I've only had 4 hours Vista experience so I'll apologize up front if this has been answered in another question. Is there a fix for this?
