If your product trial launches with a launch window that gives you options to buy, activate, try, or access more information from here, you can use the following steps to unlock the product into the full version.
To activate the software, you will need an 18 character unlock code, divided into two groups: XXXXXXXXXX-XXXXXXXX. If you do not have this code, you can purchase a copy from the "Buy" button that appears on your launch page.
Once you have the unlock code, click on the "Activate" button and enter the code into the window that appears. Once you have entered the code, click on activate to unlock your product.
If successful, a dialog box will appear confirming that you have activated the program. Restart the program before using PhotoImpact X3.
