CMA 1.5.0.2009 Crash on Vista

Tried installing CMA 1.5.0.2009 on 2 different Vista systems. CMA crashes immediately on both systems. Dot Net framework is all up to date and CMA 1.4.3.1789 works without issue. CMA 1.5 installs and works fine on my XP Pro system.

Here is the crash report from Vista:
