I'll spill the beans on how I did it:
Create a text file called vernum.txt and pack it with your game. Inside include the value (version of the game) thats it. So;
1.2
When you have an update ready upload the installer exe to your server with an incremental filename, example setup13.exe (version 1.3) also upload to a folder on your server a copy of vernum.txt and put inside it 1.3, rename the destination as newver.txt
Compare the 2 values in the text files, if vernum.txt (installed) is equal or greater then next frame. If not, update frame.
Inside your update frame then download the setup13.exe, once download is complete, launch setup13.exe, end application. User will update then.
If this doesn't make sense fire me any questions, if I get round to it I may make a more suitable tutorial or widget.
