Sorry, only one Zbrush instance

Hi, we have 4 licenses for Zbrush 4r4, currently none will run. About half the time it hangs with 25% CPU usage, the other half produces an error:

“Sorry, only one Zbrush instance may be launched from the same directory.”

There’s only ony one instance trying to run. Reboots don’t fix the problem, already running as admin.
Anyone know of any solutions?

Thanks

I have the SAME PROBLEM… I think the problem is caused by GOZ that try to run a second instance of zbrush.

Did you eventually find a solution to this issue? I’m having the same issue and nothing is working, re-installing, cleaning registry etc all failed.

I had the same trouble you did but i managed to resolve it by just running as administrator on my system. might work for you, hope it does, it was very frustrating.
