Having a problem when trying to compile a WINUI version of MAME, When everything is all set and I hit the Go button, nothing happens. When compiling a normal non-UI version of MAME, I have no problems, so I know that the issue is with MAME Compiler 64. I have also tried it on two computers with the same results. This used to work perfectly - I have used MAME Compiler 64 many many times. Maybe it is a problem with the newish version of .net Framework 4.5.1 that was recently installed? - J*
