Struggling to get Thorlabs Motorized Filter Flip Mount working

[egdeist]

Hello,
I am brand new to Instrumental and trying to get it working with a Thoralbs MFF101 flip-in mirror mount using your driver. I am not able to get it to show up with list_instruments(). I do see 3 National Instruments PXI and PCI devices. If I run
import instrumental.drivers.motion.filter_flipper I get the error
"OSError: cannot load library 'Thorlabs.MotionControl.FilterFlipper.dll' error 0x7e. Additionally, ctypes.util.find_library() did not manage to locate a library called 'Thorlabs.MotionControl.FilterFlipper.dll'"
I have put 'Thorlabs.MotionControl.FilterFlipper.dll' and 'Thorlabs.MotionControl.DeviceManager.dll' in the path using sys.path.insert such that sys.path gives
[ 'C:\Program Files\Thorlabs\Kinesis\Thorlabs.MotionControl.FilterFlipper.dll',
'C:\Program Files\Thorlabs\Kinesis\Thorlabs.MotionControl.DeviceManager.dll',
'C:\Python37-32\Scripts\ipython.exe',
'c:\python37-32\python37.zip',
'c:\python37-32\DLLs',
'c:\python37-32\lib',
'c:\python37-32',
'',
'c:\python37-32\lib\site-packages',
'c:\python37-32\lib\site-packages\win32',
'c:\python37-32\lib\site-packages\win32\lib',
'c:\python37-32\lib\site-packages\Pythonwin',
'c:\python37-32\lib\site-packages\IPython\extensions',
'C:\Users\Rubidium\.ipython']
I bet I'm missing something basic - any help much appreciated!
Thanks,
Emma

I'm not 100% sure, but I don't think adding the files via Python's sys.path will work. Try adding it to the Windows PATH variable directly.
