Start .net Exe from Word VBA macro

[texMan]

Hi,

whenever I start my App (Windows Form app) from a Word VBA macro, it crashes without a message. But it works, when I use the same command from the command prompt.

Example Code:
**************************
Sub Test
Dim cfile As string

Set wshshell = CreateObject ("WScript.Shell")

cFile = """C:\ Program Files (x86)\ myProgram CP\start.exe"""

wshshell.Run cfile, 1, true
Set wshshell = Nothing

End Sub
**************************

Does anyone have a hint?

Greetings, Jürgen
