I've made a game that uses a timer control (the only vb component control) and then uses directx 7.0a. (only direct draw). I'm trying to distribute it to users. I make the package, and the folks are getting and installing directx okay, and the package is doing its setup into its directory with no problems. Everything appears to be going okay in installation. Then when they go to run the program. It goes to black screen and hangs. I've heard DLL's can cause a lot of problems, and I wonder if I should suspect this, or is it perhaps a program problem? How would I know? How can I tell, when they run it, if they're getting a direct x error, a dll error, of a program error? If you don't have any help specific to what I've described. I'd still like to hear about other installation/distribution difficulties that other folk have had. ANY help would be appreciated, Thanks loads ape
