Happy to help troubleshoot on the other issue, not familiar with Python but am a software dev so if you need me to do anything that will shed light let me know.
Will try running as an elevated powershell later... shouldn't matter for that folder location but just in case.
Finished install, however it appears the package is failing 2 of its internall tests and passing 34.
Providing complete Powershell output, Galaxy 2.0 still not seeing the interface so presume these 2 failures are preventing integration still.
I did notice it forced a downgrade of pip from 2.2 to 1.1 not sure if that is a requirement to use that specific version.
