Don’t re-invent the wheel ....  Something you are taught all your life when you work in software development ..  For tumblripper i wrote my own “update manager” . Big word for a webrequest and a comparison followed by a popup. Recently when downloading a software (terribly sorry, i cannot remember what it was), i saw some files go thru with a strange filename, i went to check it out, and found SQUIRREL . An update manager that kinda works like Microsoft’s Click-Once (which was a good idea, but never really worked that well for me). It’s pretty much the same approach, you don’t need Administrative privileges to install software ( as it goes in your appData directory), and setup is straightforward (actually, it doesn’t ask you anything, you could call it a silent install). I’m pretty happy with it so far, even if latest update (1.5) just brakes Visual Studio integration (and honestly they should have a VS plugin anyways instead of having to manually edit your project files).
