Installed Enterprise Developer 8.0 on Windows 11 machine - Compiles Fail, Can't find most Copybooks

I upgraded from Windows 10 to Windows 11 by getting a whole new machine.  I downloaded Enterprise Developer 8.0 and Patch 18 on top of Visual Studio 2019 and tried to build a few programs.  The few I've tried all failed - most but not all of the copybooks can't be located.  What is happening here?  I've never had a problem with previous upgrades, with of Windows versions or more often Micro Focus.
