Upgrading CCleaner Professional to CCleaner Premium Bundle

Is possible to update a current CCleaner Professional (Single User) to CCleaner Premium Bundle?

email support@ccleaner.com , preferably from the email you used to buy Pro (or give them that email so they can track down your registration) and ask for their help with upgrading to a bundle.

Don't forget to say if you want a 1-year or 2-year bundle.

Thank you for the response. I will send them a E-Mail.
