can't install SEP driver with VTune 2018 update 1

[Junfeng_D_Intel]

I update VTune to 2018 update 1. It reports "Cannot enable Hardware Event-based Sampling due to a problem with the driver (sep*/sepdrv*). Check that the driver is running and the driver group is in the current user group list. See the "Sampling Drivers" help topic for further details."

my machine installs Windows 10

OS Name Microsoft Windows 10 Enterprise
Version 10.0.14393 Build 14393
 

I referred  to the help page, and run "amplxe-sepreg.exe -i". it fails with the following error message

amplxe-sepreg.exe -i -v

I got the problem fixed by deleting C:\Windows\System32\Drivers\socperf2_0.sys in safe mode.
