Develop it further at first

The program is a good idea, however it's not really intuitive yet, it definately needs some more development to make it more intuitive (try adding background scanning and more clear button-hints, I almost de-installed it because I thought I needed to select each file manually!), also add support for Windows 7, if needed you can add a simple resource to request running with administrative privileges instead of having people telling it to do so; on the other hand, why does it need any administrative privileges, the program doesn't need to use any elements of the system that require administrative privileges, try checking the registry keys you use etc.. I can't imagine you're at version 5 now, when looking at the program I'd rather think it's a first-beta or something, watch out using high-version numers, people might expect more of the program than it delivers at the moment!
