RelauchUsingCreateProcess::CreateProcess failed "c:\MyApp\Start.bat"

I have created a Thinapp and installed to my USB (drive E). When I try to start using Start.exe which tries to launch Start.bat I get the Error: .

When I run from the install to and run from the hard drive of the computer that the USB is using the ThinApp works fine. The hard drive is C: as is the virtual drive letter (the drive letter from which the ThinApp was created in a VMWare Workstation).

Is this a permissions issue or a drive letter issue?

Thx, Joe
