This is similar to answer above, which provided the vital clue. Open Contents/Resources/AppParams.pva in an editor (e.g., TextEdit), and change the value of the App Path property to the absolute path in the virtual machine to the *.bat file, rather than the application.Right-click MyApplication -myArg.app and choose 'Show Package Contents*.Duplicate the MyApplication.app application bundle and rename the duplicate MyApplication -arg.app.Navigate to $(HOME)/Applications (Parallels)/VMNAME Applications, where VMNAME is the name of a virtual machine.Start '' 'C:\Program Files (x86)\MyApplication.exe' -myArg Create a *.bat file for each possible set of parameters.This approach is a hack, but works with the least expensive version of Parallels.
