Revit can't open architectural template to start a new project

[Anonymous]

I recently bought and installed Revit 2020. I open the program, click new > architectural template > ok. Then I get "An unknown error occurred while accessing C:\ProgramData\Autodesk\RLT2020|Templates\Generic\Default_M_ENU.rte.

Can you load/set path to a different "Default" Template via "Browse"?  

I believe the path should be ...RVT 2020\Templates\US Metric\Default Metric
