And how do I give full perms?Permissions issue, you need to give your account full permissions for the folder(s) involved or windows won't give access. As for how these got changed, who knows, but it happens. As a general rule never install to any "Program Files" folder, this just aggravates the problem.
I am on my admin account, and all permissions are on for the file. Still cannot paste my backup .exe into the file.Hopefully this helps, but nothing is certain with windows; be sure to do this from admin account, or you may get that irritating message "you do not have permission to change permissions".
Making the folder an archive actually worked! Thank you so much, you are a lifesaver!Check that your folder is not READ ONLY (right mouse click on folder to check) then make a zip/7z archive of your gtr2 game folder then extract your game archive at the root of one of your drives like c:\gtr2 or c:\Games\GTR2
if you installed from DVD then DO NOT KEEP DEFAULT INSTALL PATH IN C:\Program Files\... but change it to c:\GTR2 or c:\Games\GTR2
Other than that it could be a bad sector on your drive (you can run CHKDSK to check) or a virus/malware maybe
