Can't run program in guest OS

Hi,

I'm trying to run a program (a .exe) file in a VM via vCO using executeCommandInGuest.

The thing is that the .exe file starts a UI to show the progress (not asking for input) when running it locally. When I call the script from vCO I get the following error:

Error while executing command (Can't execute command: InternalError: A general system error occurred: A program could not run on the guest operating system (Dynamic Script Module name : executeCommandInGuest#40) (Dynamic Script Module name : executeCommandInGuest#46))

If I try to call a .bat file in the VM that starts the program the WF runs but the .exe file is never started in the VM.

If I specify to run another .exe e.g. ping.exe the command WF completes and if I specify a .bat file that calls ping.exe it also completes successfully.

There is no silent mode for the .exe I need to run.

Any help would be much appreciated.

Thanks

Magnus
