You can access your Avanquest account by clicking HERE. Log in using your email address and password, then navigate through "View orders" and select the date of your order from the "Complete Orders" list.
You can download the installation file of the program from there and securely send an email with the installation code (also known as serial/license number) to your private email address. You can access the invoice form, in a printer-friendly format, as well.
Note: Avanquest Software, purchased through other web stores or retailers will not create an account in our Avanquest membership area, nor will those orders appear in your list with products.
