but i need a mach 4 istallations file for win xp
my controller computer just won't let anymore and i need the parts outside

maybe someone here can help me
the support does not answer

thanks a lot
greetings sven

Have you checked the OS requirements for Mach4 on the NFS website?  I suspect that they haven't supported it on XP for some time.
