Hi everybody,
I have a problem with the License and my Houdini 17 installation. After starting the program I had to install the Houdini Apprentice license, I installed itself successfully, but if I hit the Run button afterwards the License Administrator opens up again and I need to install the license again. This happens all the time.

I have a MacBook with the macOS 10.14.

Does anybody know how to get out of that circle?
