"Contacting McNeel Servers" forever when trying to run WIP

This happened after the last Windows major update. Entering the WIP license key also doesn’t work (“Rhino will now exit” message). Any ideas how to fix this ?



Hi Jarek,

I apologize for the inconvenience. Could you PM (or email me at aj@mcneel.com) me the files in the following locations?

You can type the following file paths in explorer:

%appdata%\McNeel\Rhinoceros\6.0\License Manager\Licenses
%programdata%\McNeel\Rhinoceros\6.0\License Manager\Licenses

hi AJ - I PM’d you the files. thanks!


Solved. The problem was Chrome was left as default browser under Windows Settings, even though I had to remove it since with the latest Windows Update it became super slow and unstable. Changing the default browser to another one that is installed solved the licensing problem (ability to login with browser pop-up window)…

thanks AJ for your help!
