I use the borrowed license from our license server, but today I cannot start my ZW3D after windows being automatically updated. Why and how can I make ZW3D work again?

Solution:

The license may be destroyed by the windows update. In this case, customers can apply for a floating license to use ZW3D, and wait for the expiration of the borrowed license. It will return to the server once it is expired.

For windows 10, our suggestion for all of our users is to update manually instead of auto-updating. Return the license first before updating, and activate again after that. Of course, the floating license will not be affected.
