eightbit and Papaschtroumpf.
I have no idea why you are getting the runtime error 5.
I can only sugest a few things to try to see what happens.
1. MAMEWAH Set-up uses the systems regisry to store info. If the program doesn't dispaly anything apart from the error (A window should appear asking where MAMEWAH.EXE is installed) then there shouldn't be anything in the resitry, check 'HKEY_CURRENT_USER,Software,VB and VBA Program settings,MAMEWAHSetup' if MAMEWAHSetup exists you could try deleting it (It should not do any harm).
2. In the MAMEWAH folder move your CFG files to a back up folder and run MAMEWAH as though it was a new install, so that you get the blank config files, and try running Set-up to see if you still get the same error. But if you do not get the first window to display I can't see this being the problem.
If none of the above work the problem is in the first few line of my code and all that happens is the sound is setup and the tab strip for the differant pages.
I'll keep diging to see if I come up with anything else
