    I tried to install this new build as previous ones, after a clean uninstall of previous one and deleting EVERY TRACES in my system of Kaspersky, as always...

    The installing took long, in the final window installing bar process -> it remained in 10 seconds to finish during loooog minutes, then in 5 seconds to finish long minutes... after more than 20 minutes waiting, I cancelled the installation, but still the cancelling process took long, so I had to kill manually 1 of the msi installers processes... then rebooted the system and ran again KTS2020b933 installer, after 3 or 4 reboots finally I could manage to finish the installation successfully.

    I noticed the when i start up KTS there will be 2 avp.exe processes started and keep running and when i run an update a third will be started and keep running event after the update is finished.

    I recorded dumps manually with 3 avp.exe processes runing and added some traces from starting KTS up and closing KTS again and starting KTS up again .
