Here is the idea I have. 1. The program checks if there is a new copy of itself on a remote location. 2. If so then the program downloads the new copy with a temporary name. 3. Then the program creates a batch file that would delete the original, rename the new version and finally run the new version. For this to work I need to run the batch file after the program exits (otherwise a file sharing error occurs). But I have no idea on how to do it. Does anyone has a brainstorm on how to do it?

Hope, this helps :D

my advice: have the main program CreateProcess an "updater" program which will do the deleting/replacing. that way you have more control over things - you can check whether the old program has terminated and if not wait for it to finish.
