Hello and thank you for posting.
InPixio Photo software comes with a single-user license. You are allowed to install the application on one computer only. If the software asks you to order it again, remove the InPixio software from the Control Panel and restart your computer.
Please download the setup file again, using the link in the order confirmation e-mail or access you Avanquest account.
Make sure the download was successful, start the installation process and copy your license key.
If the software rejects the key (serial number), please check its spelling.
