I get a MS Visual C++ Runtime error when I audit and MAMEUI32 shuts down. All of my runtimes are up to date. I'm using MAMEUI32 0.171 on XP.
These are my runtimes. Microsoft Visual C++ 2010 x86 Redistributable - 10.0.40219 Microsoft Visual C++ 2012 Redistributable (x86) - 11.0.61030 Microsoft Visual C++ 2013 Redistributable (x86) - 12.0.30501 Microsoft Visual C++ 2015 Redistributable (x86) - 14.0.23026
