MindManger 21 will not install
MindManger is not working properly with use of proxies.
Installation runs to nearly end then it stops with "No internet connection".
Further investigation show a link to https://client.wns.windows.com.
An extra call to this site shows "An error occurred during a connection to client.wns.windows.com" cause this site does not show a certificate.
So installation stop an no work is possible.
