I've decided to add auto-update functionality to one of my applications and was looking for any existing solutions that compare the current running version with the latest version that is then downloaded from the web.
I know Sparkle on Mac OSX which is very nice and powerful, but was wondering whether there is something similar for Win32/MFC?
I just stumpled accross WinSparkle which is an early stage but looks very promising.
There is open source project WIPT inspired by APT of Debian Linux. However, the project seems to be abandoned.
I've never used it, but WiX provides ClickThrough. Might be worth a look.
AbstractSpoon uses "Software Update Wizard" from here for their awesome ToDoList MFC app.
I found two more projects aimed at solving this: http://sevenupdate.sourceforge.net/ and Google's Omaha but it's not clear either of them has any external users yet, so this question is apparently still open. I too am looking for a solution....
Another .NET one: SparkleDotNet
