All organizations which use VSys One are given an organization-specific serial number, which is paired with their organization name. VSys won't start without that company name/serial number combination, or if either value is incorrect.
Some serial numbers - for demonstration versions or for those whose account is not yet paid up - have built-in expiration dates. After the expiration date, VSys will no longer start until a new registration code is entered.
Enter a code by selecting the Enter VSys One registration codes link from the Administrator tools panel. As appropriate, use the (add) hyperlink to enter additional registration codes to enable add-on products like VSys Live.
