I have downloaded (and re-downloaded) the free versions for v4.0.11, v4.1.9 beta and v3.8.12. When attempting to import the package, all of them give me the same error:
Failed to import package with error: Couldn't decompress package
This occurs in both new and existing projects based off of my root drive (should not be a filepath issue with naming/length). Any help with being able to import the package is appreciated.
NOTE: I am using Unity 2017.3, I have not tried it on an older version yet but will attempt to do so.
