I just loaded Windows 7 Home Premium 64 bit. The problem is that it is telling me that I don't have permission to open some folders and/or files and when I select large icons they don't display the picture. Also when I try to click a link in my email I get a message that the operation has been canceled due to restrictions in effect on this computer. All of these things worked right on Windows 7 32 bit. I am a retired programmer/Graphics Designer and have not had any experience with permissions. I have been on multiple types of computers since 1981.
