To install properly: 1. ***--> SIMPLY PRESS "OK" <--*** when the desktop preferences window opens before the install finishes. 2. The Windows Active Desktop must be enabled to run uDesktop. It's on by default, so if you don't know what it is, you should be fine. 3. Cookies must be enabled in Internet Explorer. Again, they are by default and you're fine if you don't know what cookies are. 4. If uDesktop does not show up on your desktop background after install, log out and log in again.
