I searched around, but couldn't find anything, so I guess I'll post. I've created a proggie that modifies registry keys for a game of mine (half-life). I'm running Windows 98, but my friend is running XP. I gave him the program, and it will query correctly, but it won't actually change the key. I assume the problem has something to do with the access rights to the registry with XP's security stuff... or something like that. Anyway, if you can help me out with some codin' that I can use to set the security settings (I can get his username 'n password if needed) so I can make a version of this program for him. Thx!
