1) Ensure the "LCWSoft License Manager" addon from https://www.lcwsoft.com/download/category/3/LCWSoft-License-Manager.html is up to date. The listing will have the version number in the title and should match that under Setup > Addon Modules (if using WHMCS 7.10 or older) or Configuration > System Settings > Addon Modules (if using WHMCS 8.0 or newer). If it does not, you need to download and re-upload the new version.
2) Upload the contents of the "upload_me" folder to the main folder in your WHMCS installation.
3) Click Configure for "Open Ticket on Cancellation Request" under Setup > Addon Modules (if using WHMCS 7.10 or older) or Configuration > System Settings > Addon Modules (if using WHMCS 8.0 or newer), configure any new settings, click "Save Changes", and enjoy!
