How to Restart the zSpace tracking server?

unity3d show"Runtime Error ! R6025, pure virtual call
then unity editor crashed

Sorry to hear your editor crashed. I have seen that error before, but I can’t recall for sure whether restarting the tracking server was the solution. However, since that’s your question, and I assume you don’t want to restart the computer, the simplest way to restart tracking is through task manager.

The tracking server should restart itself, but if not, it’s located here.
C:\Program Files\zSpace\System\bin\x64\zSTrackingService64.exe

These instructions assume you possess a 300/AIO model. Instructions for the laptop model may differ.

zSpace tracking server shut down due to my Unity3d crashed,i fixed up it by reinstalling the Unity.
