# Renewing and Updating Licenses

A Parallels Desktop Business or Enterprise Edition license is renewed automatically online. When Parallels Desktop is running on a Mac, it sends a license renewal request to the Parallels Licensing Server at random intervals. Once a license update is available, it is automatically downloaded and installed. Please note that if the license key expires, Parallels Desktop will continue to run on a Mac until it checks in with the Parallels Licensing Server. This could be anywhere from a few minutes to seven days.

Parallels Desktop uses port 443 (the standard SSL port) to communicate with the Parallels Licensing Server from which it obtains license updates.
