how software licensing works

A TSSI Software licence is specific to a particular PC. When a TSSI software product is installed and run, a message is displayed showing the fact that the product is unlicensed, and showing a window which contains fields for you to enter User Name, Company Name, and Expiry date. The window also shows a 16 character "Computer ID" value, specific to the actual PC on which the software is installed.

To get a licence contact the TSSI helpdesk with the values for each of these fields (for a permanent licence, enter a date a long way into the future, e.g. "31/12/2099"). TSSI will respond with a new 16 character "Licence String" value. Enter this into the "Licence String" field, click on the "Register" button, and the product is now licensed.

Note: the specific "Computer ID" is derived from a number of factors concerning the actual PC; these include the hard disk drive, the operating system installation, and the network domain details. If any of these change (e.g. domain name changes), the licence will cease to function, as the "Computer ID" value will have changed. If this is the case, contact the TSSI helpdesk for assistance and include details of any changes made.
