Saw this posted in the ZennoPoster Mental Power thread but looks like they were too lazy to open a bug report 
MP installed successfully but on running the project maker it crashes after the "Load Modules" stage.
EventType : clr20r3 P1 : projectmaker.exe P2 : 4.0.0.0 P3 : 4fbfe9b8
P4 : projectmaker P5 : 4.0.0.0 P6 : 4fbfe9b8 P7 : 7af3 P8 : 66
P9 : system.dllnotfoundexception
Zennoposter starts normally.
If it is related - I had to reinstall ZP back in April because of a Phalanger issue. Probably not related, but detail included anyway.
OS is XP Home Edtion SP3.
