unexpected end of JSON input

I have tried installing the nrf connect 3.11.1 on 2 different windows 10 machines.  Both are clean windows 10 installs. The hard drives were wiped and windows reinstalled.

When I try to install the tool chain manager I get the error "unexpected end of JSON input". 

I tried the recommended solutions from both of these tickets.

 Unexpected end of JSON Input Error after installing nRFConnect for Desktop 

 Unexpected end of JSON Input Error after installing nRFConnect for Desktop 3.11.1 

Neither one worked.

The other apps all install correctly only the tool chain manager fails.

Is there some other dependency I need to install?
