To upgrade to the most current version of any of our products from an older version you must validate your upgrade price by entering your current serial number in the applicable field in the Store. If the serial number is valid, the store will proceed with the upgrade sale. When you have completed your transaction, you will be immediately emailed an e-receipt with a new serial number and download link for the latest version of the software you are ordering. If you are using a trial copy, you can use your new serial number to register the trial which effectively turns it into a non-expiring copy. Make sure to check your spam filter if you don’t receive the e-receipt.
