i have validity till sep'09 on one activation code for 3 computers. I was to format one of them. after formatting and while trying to activate with the activation code supplied to me and connecting net there was an message that the activation nos are completed. But my system was the first connected among the three.
now how can activate with my old license key supplied to me for 3 computers as it is.
please help me on this issue.

Go to https://activation.kaspersky.com and activate your code. Download the license file and store it on a safe place.

The you can use this key-file in future.

We have a similar issue. We have a workstation that already had Kaspersky on it. I reformatted it, reinstalled windows XP PRO, named the workstation exactly what it was named before, installed Kaspersky and Kaspersky will not update. We have logged onto the server from that station and installed Kasper with no luck, We have tried pushing Kasper out from the server to that station and no luck. It will give us a message that Kaspersky is already on that station and we cant even force it into an update. All we did was a simply rebuild of a user workstation. Why is it such a pain in the buttocks to get this going? We are going to be doing this with several workstations in order to deploy them in a different location. Help.... Please... my head is starting to hurt
