It is a “reusable” download (you can buy a CD too by paying extra). The installer exe file that you download can be used again to install the product on any other computer. It is better to “save” the paid version installer exe file to a safe location (or burn it to a CD) so that you can use it again.
What if you lost the download? If you lose the program or key information, we have a special web site, support.whizfolders.com, where you can login and get the download and the key again. This facility is free for a year after your purchase. Some people also call this an upgrade-protection or maintenance. If any updates or upgrades are released within the next year after your purchase, you get them for free by using the same procedure. (For purchases earlier than Jan 22, 2010, the free upgrade period is 2 years)
However, if your upgrade period has expired, the web site asks you to renew your upgrade subscription by paying an upgrade fee. A special link to an upgrade order form is provided.
By using the same web site, the Pro version users can also upgrade to the Deluxe version at a special price.
