Not having sufficient permissions to save Rhino file after importing

When importing a Rhino 6 file that has a long filename, an error appears stating that there are insufficient permissions to save the file.

1. Download the attached .3dm [Link Removed]
2. Open the UE4 Editor and create a new blank Unreal Studio project
3. Navigate to the Import DataSmith button, click the dropdown arrow, and select Import CAD
4. Import the downloaded .3dm file

Results: The imported .3dm file is unable to be saved due to insufficient permissions

Expected: The imported .3dm file is able to be saved without issue

How can I solve Unreal Studio issues with saving permissions?
