Hello,
Thank you for your reply.
I am answering your questions in BOLD:
I hope installing SEP using full admin rights.
Yes, that is correct, I am installing using full administrative rights to the system in question.
Could you attach SEP_Inst.log file, it will be available under %temp% directory.
The file has been attached as "SEP_Inst.log_.txt".
You have installed any other antivirus software on this before?
The system in question used to have Norton Internet Security 2010. I have since removed the software and ran the "Cleanwipe" utility per my comment a few days ago.
How much free space is available on C drive?
The system has approximately 166GB of free space. You may review the "HardDiskSpace.png" image for confirmation.
By any chance do you have legacy SEP 11.x version setup.
I don't understand the question, are you asking me if I have an old version available to install or if I am using an old version?
I am currently trying to install version "12.1.4013.4013".
Let me know what else I can provide.
Thank you for your time.
