Fixed the issue.  First one is the system variable for C:\Windows\System32\ was missing. https://cryptomator.freshdesk.com/support/solutions/articles/16000003675--reg-is-not-recognized-as-an-internal-or-external-command   Second issue I ran into was I needed to install a version of Visual Studio that included C++.   https://www.visualstudio.com/downloads/ Once that was done I successfully installed and ran the Screeps server through powershell.
