Hi! Tried to reboot the PC with only essential services running. During installation, killing all unnecessary processes (even explorer). I think the rollback is started after these errors: MSI (s) (80! B [14:53:00:986]: Creating MSIHANDLE (33 of type 790531 for thread 4024 ESET: Returing from CA InstSupp! InstallDriverPackages, with status 1068 MSI (s) (80!
