Kaspersky - how Kaspersky Lab products work with trial key files

Concerning to:

Kaspersky Anti-Virus 7.0 (all builds) Kaspersky Internet Security 7.0 (all builds) Kaspersky Anti-Virus 6.0 (all builds) Kaspersky Internet Security 6.0 (all builds) Kaspersky Anti-Virus 6.0 for Windows Workstations (all builds) Kaspersky Anti-Virus 6.0 SOS Kaspersky Anti-Virus 6.0 for Windows Servers (all builds) When Kaspersky Anti-Virus version 6.0\7.0 works with a trial key file, the key file may expire prematurely, if after trial key installation:

• the system date was set forward for the time period which equals or exceeds the validity period of a trial key file and then it was set backward to its initial state – the validity period of a trial key expires and no other trial key can be installed.

This is a peculiar feature of the licensing library of Kaspersky Anti-Virus version 6.0\7.0. If another key file is already activated and is in use, then when you try to activate another key file the following error may occur:

• License key file "C:\XXXXXXXX.key" cannot be added. License validity period has expired.

The error may occur if:

• in Kaspersky Anti-Virus version 6.0\7.0 the current key is commercial and you try to add a trial key file as a reserve one.
• in Kaspersky Anti-Virus version 6.0\7.0 the current key is commercial one and as a reserve one you try to add commercial key file whose validity period expires (has already expired) earlier than the installed commercial key.
