Hello,   
  
 I place 2 “Run MSTest” actions to “Async action Group” action. When I run project - I get only new folders with output files for tests, but have no .trx files (obviously i should get 2 .trx files - 1 files for each MSTest run).   
 Notes:   
 1) Both of “Run MSTest” actions are very short (there are a few tests in dlls) and folders with tests output have names like “User\_Machine 2013-04-10 12\_22\_34” and “User\_Machine 2013-04-10 12\_22\_34[1]”.   
 2) I specified different names for result file for each Run MSTest action.   
 3) If run those Run MSTest actions without “Async action Group” action - everything works perfect   
  
 Regards,   
 Elena

Can you show the settings you have for the action? What version of FinalBuilder, what version of MSTest?
