Hi
I have been using VIP To Do for the last 3 months on a USB Stick. It works great!!!!
Install was very easy:
1. Download and install to your removable drive.
2. On install do not create shortcuts.
3. Save your data base and your License to your removable drive.
Some time when changing machines it will ask you to point the the Dbase file.
Great Product!http://www.todolistsoft.com/bitrix/images/forum/smile/icon_biggrin.gif
