Power BI Desktop not Launching

Was happily using PowerBi just a bit ago, and then it froze, along with my computer, ended up doing a hard restart, and now Power BI won't launch.   Un-installed, reinstalled.  Tried the  PBIDesktop.msi version and PBIDesktop_x64.msi, still the same error.

Error Message:

File contains corrupted data.

Stack Trace:

System.IO.FileFormatException: File contains corrupted data.
