Sonic, I read through this thread and I have 303en doing a silent install without rebooting by applying the 'LastStart' entry to the reg. I would like someway to automate the first update which currently requires another reboot to be functional. I'm not concerned about the next reboot, but I would like to automate getting the initial update as it is currently approximately 8MB. My first attempt has been a failure so far. I pulled the Bases directory from C:\Documents and Settings\All Users\Application Data\Kaspersky Lab\AVP6\Bases\ and zipped it up. On a second system with a fresh KAV6 install, I copied the Bases.zip file over and modified the Update Servers. I unchecked the Kaspersky Lab's update servers and added the path to the zipped version of the Bases directory from the other system (see attached image). This works, so I attempted to script my solution by using the following registry entry before running the update: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\KasperskyLab\AVP6\profiles\Updater\settings\Sources\0000] "Enable"=dword:00000001 "Plain"=dword:00000001 "Path"="C:\\Documents and Settings\\Administrator\\Desktop\\Bases.zip" [HKEY_LOCAL_MACHINE\SOFTWARE\KasperskyLab\AVP6\profiles\Updater\settings] "UseInternalSources"=dword:00000000 After applying the registry entry above, I use 'avp UPDATE' from the command prompt. This worked too, as it applied all the updates from the zipped file. The problem is getting the registry back to normal afterwards without manual intervention. Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\KasperskyLab\AVP6\profiles\Updater\settings\Sources] [HKEY_LOCAL_MACHINE\SOFTWARE\KasperskyLab\AVP6\profiles\Updater\settings] "UseInternalSources"=dword:00000001 Once KAV6 has been installed and updated, attempts to modify the registry return 'access denied'. Any ideas how to get around this and get the system back to normal, or perhaps an entirely different approach?
