Upgrading Serial Numbers
Upgrade an Existing Arc2Earth Serial Number
After a purchase, it is sometimes necessary to upgrade your existing Arc2Earth Serial Number to new one. This can occur when you've used the Community Edition or after your Trial has expired. Upgrading a Serial Number is easy and can be accomplished directly in ArcMAP
1) From the main Arc2Earth toolbar, goto the Help menu and select the "Upgrade License" menu option
2) It will prompt you to overwrite your existing license, click OK to continue. Once you click OK, you cannot go back to your original license without having the old serial number.
3) Fill in your name, company name and serial number in the appropriate text boxes
4) Click Register. You may need to restart ArcMap to see the new license
