If you no longer wish to use DBT on a system, you MUST remove it from that PC in order to restore your user count.
The procedure for removing DBT from your system is done via Windows Add/Remove Programs accessible from the Control Panel.
Provided you are connected to the Internet, (without firewall restrictions) the removal process will normally adjust your activation count, ensuring that you can activate later on another system.
In the event you are NOT connected to the Internet, a text file will be placed on your desktop with de-activation information. (Note: The file name may be slightly different depending on the version you are removing.)
This file may be e-mailed or printed and faxed to Duxbury Systems whereupon your License count will be adjusted accordingly.
