This article will help you download and place the license file.
Step 1 - Download license file
Log in to the Checkbox Support portal at https://www.checkbox.com/support/support-login/. After logging, in you will land on the https://help.checkbox.com/hc/en-us page. Along the right-hand side, highlighted in gray, will be a section where you can download your Checkbox V7 license file. Click the link to download it.
Step 2 - Place the license file in the appropriate folder
In your File Explorer, move the Checkbox license file to the api\bin and also copy it into the checkbox-service folder. If you are replacing an old or trial license with a new production license, make sure you remove the old license file from each location.
Step 3 - Restart IIS
IIS may cache the licensing DLLs, so we recommend that you restart your site/IIS once you have replaced a license file.
