If I continue this uninstaller, will it force a reboot?

On trying to uninstall Teracopy, it warns me that a restart is needed:

The setup must update files or services that cannot be updated while the system is running. If you choose to continue, a reboot will be required to complete the setup.

Will clicking “OK” cause a reboot, or is it just warning me that the program won’t be cleaned up until after the next reboot?
