I tried Randor's Do Loop with WaitForSingleOject, but it didn't work out.

Does the CloseHandle delete the memset, or do I have to do that manually?

Well it works like a rolex now. I can cancel the installation, and it exits clean. I put my cosmetics in, but changed it to a more simple format. I put a flipflop in, but can't remember how to flipflop with a simple command. bFlipFlop++ or something.

bool b = true;
while(1)
{
    b = !b;

The sample should give you a good idea of what I'm up to, perhaps there's something in the message that can tell me if the user canceled the operation, versus the operation exiting clean.
