When moving to a new Windows system, either after getting a new computer or reinstalling Windows, you may be tempted to copy a program’s folder to your new system just like you’d copy your files. But this normally won’t work.
This is very interesting. I have done just what you have said is very hard to do just by copying the Program Folder, the User folders, and the main registry keys to a cd and then installing them that way. Of course this is on Windows XP and earlier, but it does work on the older programs.
But since you are talking about the overblown Windows Phone OS where no programs will run correctly then this is a moot point.
