yes start fails, but start also fails if you provide it a path with a space, without being quoted...

````
START ['title'] [/D pad] [/I] [/MIN] [/MAX] [/SEPARATE | /SHARED]
      [/LOW | /NORMAL | /HIGH | /REALTIME | /ABOVENORMAL | /BELOWNORMAL]
      [/NODE <NUMA-knooppunt>] [/AFFINITY <hex. affiniteitsmasker>] [/WAIT]
      [/B] [opdracht/programma] [parameters]

The first quoted parameter will be the window title. If you don't look closely you'll completely miss it. I'll update the code to work properly
