Hey there  
I have got a problem with the driver:

```auto
  File "C:\Users\Labor\Skripts.py\untitled2.py", line 10, in <module>
    vin_device = cvb.DeviceFactory.open(cvb.install_path() + "C:\Program Files\STEMMER IMAGING\Common Vision Blox\Drivers\GenICam.vin")

RuntimeError: {C-API call failed} ({LoadImageFileW})

```

Where does this error come from?  
Thx in advance

Hi @raphy,

probably because you add the CVB install path to an absolute path:  
`cvb.install_path() + “C:\Program Files\`  
please just use one of the two 🙂
