I purchased the download for Windows 7 64 bit to upgrade my XP 32 bit and "unloaded the box". At the end of the unload I get an error message that says, "We are unable to create or save new files in the folder in which this application was downloaded. Please check the folder properties to make sure that you have security permission on the folder to write files and that the folder is not read-only." How can this be corrected? I have XP installed on my old hard drive but bought a new one and hooked it up. I am attempting to install Win 7 on the new hard drive. Then, when I attempt to run the installer I get the error message "F:\expandedSetup\setup.exe is not a valid Win32 application" . Is this installer not compatible with the 32 bit version of XP?
