I tried to stop resident protection in ESET, after restart PC i just rename folder C:\Program Files\ESET\ESET Security to ESET Security_old, next restart, and then it can stop service ekrn and install new eset. This worked on 2 PCs. Other two that i tested now have problem to install new eset, because error "You dont have privilege to install system services)" or something like that. So half way solution :(.
