How to troubleshoot Redshift License is not working

Redshift 3D supports a set of rendering features not found in other GPU renderers such as point-based GI, flexible shader graphs, out-of-core texturing and out-of-core geometry. However, sometimes you might encounter the issue where “Redshift license is not working”. Let’s find out how to troubleshoot it.

1. Check your internet connection

The issue might be caused by an unstable internet connection. You should check if it’s connected, or you can change to a cable internet instead of wifi for a stable connection.

2. Redshift Licensing Tool error: Failed to repair license

This is an extremely rare error! Please try the following steps to try to resolve it:

  • Try deleting the file redshift-core.lic file in the folder C:\ProgramData\Redshift and try activating again
  • If the above doesn’t work, also try deleting C:\ProgramData\Reprise\redshift\redshift-core (please do that even if the folder appears to be empty!)

3. Render-time error: License found but is not valid for this machine

This error can appear with node-locked licenses. It basically means that the license needs to be refreshed in the Redshift Licensing Tool. Please run the tool the deactivate/reactivate your license. If this doesn’t solve the issue, please try deleting the file redshift-core.lic file in the folder C:\ProgramData\Redshift and try activating again
