I get the following error message when attempting to run an inversion.
Run Inversion:
The service failed to run the inversion.
The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.
Resolution:
Copy your project to a new location with a shorter file path eg: your desktop or local C:\ drive.
Root Cause
In Windows the maximum length for a file path is defined as 260 characters.
