If you own one of our notation products, but receive an error that indicates you have no products authorized on your account when you try to upgrade online, your product is most likely already registered on a duplicate account in our database. In most cases, these accounts were created under an older e-mail address.


If this is the case, it is possible for MakeMusic to merge the duplicate accounts. To request this, please contact Customer Success team by submitting a support ticket. Be sure to provide information that will help us find your previous account, such as your product serial number or older e-mail addresses. Also, let us know which contact information you wish to keep current (name, addresses, password, etc.).
