I want to install SEP on a Windows 8 x64 but it rollbacks with the attached log.

I have run the cleanwipe utility but again installation rollbacks.

I have attached the sep_inst.log to this forum.

Would you please kindly help to resolve the issue?

sep_inst.log is missing, kindly attach it.

showing the same symptoms in the log. Follow these steps as fo now till a fix is applied.

Until a solution is provided, you can work around this problem using one of the following:

• Disable Windows Defender before installing the SEP client
• Remove KB2781197 before installing the SEP client

Did you reboot after the patch was uninstalled|? 

in the registry delete all the registry keys below Symantec node(HKLM/software/symantec)

disble windows defender and try to install the client as unmanaged.

the problem is always present.

Dont worry we will fix it , Can you post the SIS.log found under

%AllUsersProfile%\Application Data\Symantec\Symantec Endpoint Protection\%currentversion%.105\Data\Install\logs

• Contains SIS_INST.log (Symantec Installer Log)
• Contains RORU.log (uninstall log of previous product)
• ETUPAPI.LOG
  • Important: This log used to be located in C:\Windows\ but it is now located here: C:\Windows\INF

I JUST FOUND SIS_INST.LOG under the folder :

%AllUsersProfile%\Application Data\Symantec\Symantec Endpoint Protection\%currentversion%.105\Data\Install\logs

thank you very match Rafeeq, the problem is gone and the new SEP 12.1.3 RU3 is now installed without problem and connected to the server manager.

@Rafeeq:

You could write the definitive book on SEP installation issues and how to get it installed

Thanks Brian but only with your help :) 

I only know a couple, your knowledge of the way SEP works in the registry is advanced far more than what I know.

Good news is I've been saving your comments for future reference and troubleshooting :)

Very helpful!

That was few months back. I'm saving yours now :)
