Dear developers,

 ![img_v2_32bf3ef9-97e1-497a-8291-12cfe06d9d1g](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/5/0/501506ce385e20737726183397ee96f1c778dec2.jpeg)  
When I type this command to use cli FiberTractMeasurements on my windows computer, some errors jumped, which says, can’t find xxx.dll, and cannot run the code, reinstalling the program may resolve this issue.

The answer is probably similar to this post:

On windows you provide the full path to Slicer.exe with the --launch argument to run the CLI executable.

I believe you need to put the full string with `\path\to\Slicer.exe --launch ... FiberTractMeasurements.exe` inside a single set of quotes.
