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.
