FILE_FLAG_DELETE_ON_CLOSE doesn't work

I'm trying to make a self deleting executable. By using the "spawn a clone flagged with FILE_FLAG_DELETE_ON_CLOSE" technique. (If you're not familiar with this, look here)
But the problem is, the FILE_FLAG_DELETE_ON_CLOSE flag only works if the last handle to the file that gets closed is opened with that flag. Making catch22's method inoperable. So, the question is, is there a way to get CreateProcess to open the executable using FILE_FLAG_DELETE_ON_CLOSE internally?

So why not use the DELETE_ON_CLOSE method (I don't really get which method you are trying to use, but I'm guessing it's that one)?

This is why.

Wait, CreateFile accepts the flag, not CreateProcess... oops. Sorry.
You would be right.
