Unable to open Duraction via Command on windows 7

[rwebber]

I am working on a system integration tool, that launches required software tools during a performance. When trying to launch Duration via command (direct path in cmd.exe, or via python subprocess.popen) Duration crashes.
I have no problem opening the EXE from the folder, by clicking.

The crash report:
