Rainlendar License R2lic -

"r2lic" likely refers to a license file or identifier used by Rainlendar Pro. Rainlendar Pro uses license keys to unlock the paid features; when you purchase a Pro license you receive a key (a string you enter in the app) and sometimes a small license file or token that the program recognizes. Users often see filenames or internal identifiers such as r2lic, rainlendar.license, or similar when the application stores licensing information locally.
