When trying to start the TOADS-CRUISE_2012_Mar_23_R3c.jar under windows 7 64 bit I get the following error message:

"Failes to load Main-Class manifest atrribute from C:\.... \TOADS-CRUISE_2012_Mar_23_R3c.jar" 

Is this a bug in the current version or does the jar file require special java software to be installed?

What version of MIPAV are you using? Older versions of MIPAV use older Java's, and that could be the cause.

I believe that jar was tested with mipav 5.4.2 from March 09 2012.
