Register your old and new license keys
After you've purchased license keys, you must register them in the application. For upgrades, you must register both the new license keys and the old keys that entitled you to the upgrade.
License keys for SpreadsheetConverter are purchased online in our license shop. After a completed purchase, you will have one or more license keys, character strings that begin with a three-character product code and seven four-character license key segments. Example:
To get from SpreadsheetConverter HTML version 5, Standard edition to version 6, Professional edition, you need both a version upgrade and an edition upgrade. This requires two separate purchases, giving you two separate license keys. If you also want to unlock HTML5 generation for iPhone and Android, this flavor add-on is a third purchase, giving you a third license key. You can register all three license keys at the same time, together with the original version 5 license that validates the other three.
Registering license keys in the application
All your license keys must be registered in the SpreadsheetConverter application to unlock the corresponding functionality. If you haven't already installed the version of application you have purchased license keys for, download and install SpreadsheetConverter now, before you go ahead and register your license keys.
Then start Excel, select the SpreadsheetConverter ribbon and click Help. Click "Product activation" in the Help menu.
The Product activation window allows you to register all the license keys you need to unlock all the functionality you've paid for in the application. Together with each license key, you must register the e-mail address you specified when you purchased the license key.
For upgrades, new license keys won't work without the old license keys that entitled you to each upgrade. SpreadsheetConverter needs to confirm that you have not only the upgrade license, but also the license it is upgrading.
For example, if you've upgraded from version 5 to version 6, the new key requires that you enter the old version 5 license key as well, to validate the upgrade.
Similarly, if you've purchased an edition upgrade from Standard to Professional edition, you must enter both your old Standard edition key and your new Professional edition key.
If you have lost an old license key, or if you have any other problems or questions, don't hesitate to contact our Help Center. We are here to help.
