When you notice that a newer version of Portable Offline Browser is available, please download the new installation file from our Web site: http://www.metaproducts.com

Run the downloaded installation and point it to setup files into the same directory where the previous version was installed. This will preserve all your Projects, downloaded sites and settings. There is no need to reenter the registration key if you make a minor upgrade, like from 4.4 to 4.7 version. Major upgrades, like from 4.x to 5.x version require additional key which could be purchased for some upgrade price.
