Upgrade to IIS Mod-Rewrite Pro
With this plan you can upgrade existing IIS Mod-Rewrite Standard license keys to Pro.
For technical reasons, it is not possible to upgrade activated license keys.

To de-activate IIS Mod-Rewrite, go to Start Menu > All Programs > IIS Mod-Rewrite > IIS Mod-Rewrite Control Center, open the Activation page, and click the button "De-activate". If you own a volume license key, do the same thing for all activated IIS Mod-Rewrite instances.
