Upon loading a JupyterQ notebook for a kdb project, I got an unfamiliar error.

License check failed.

There's an issue with the license manager. Check your installation carefully and/or reinstall your application.

I googled it and there's no explanation, other than to reinstall everything, which I did.

conda install -c kx kdb
conda install -c kx embedpy
conda install -c kx jupyterq

No change, still get the error. Any suggestions?

64-bit kdb requires a license to run although it is free for non-commercial use with some limitations. Have you followed the steps outlined here to get the kc.lic file downloaded?

  • I have, I've been using jupyterq for the last few months, this is a new error. I was using it a week ago but today this error pops up. I google it and I click here: https://github.com/KxSystems/jupyterq/blob/master/jupyterq_licensemgr/jupyterq_licensemgr/__init__.py It seems to be a new error. – Grant Baker Feb 12 '21 at 21:37
  • hmm yeah quite possibly a new error. May be worth emailing `ondemand@kx.com` – Matt Moore Feb 12 '21 at 21:52

Licences/binaries 'expires' occasionally. Request new one, or download new binary.

Had the same thing happen to me. You need to replace this file in your anaconda3 folder C:...\anaconda3\q\kc.lic You can do so by downloading the licence from kx: https://ondemand.kx.com/

This it is the free, non-commercial, 64-bit kdb+ on demand licence. Fill in the info and they'll email you the license.
