[@Bob Fallona] The message means that you cannot activate Agelong Tree that is installed on a USB external disc/memory stick using this type of license. The license we provided for the giveaway is a standard type, it allows to activate the program installed on a computer internal disc. However, you are welcome to purchase a portable license at our website https://genery.com. A portable license allows to activate Agelong Tree installed on a USB external memory stick/drive. The USB external memory stick/drive with the program works on any computers with Windows 7,8 or 10.
