I have never used AdvanceMame before but I did just download it and took a look at it. What immediately stands out to me is that your are pointing to the admenu.exe which is not the emulator but rather the front end. Try changing this to advmame.exe instead and see what happens.

thank you works perfectly now.

Getting this error anytime I try to launch any game from AdvanceMAME. Thanks for any help.
