Install the Sampling Drivers for Windows* Targets


To install the drivers on Windows* 7 (deprecated) and Windows* Server 2008 R2 operating systems, you must enable the SHA-2 code signing support for these systems by applying Microsoft Security update 3033929. If the security update is not installed, event-based sampling analysis types will not work properly on your system.

To verify the sampling driver is installed correctly on a Microsoft Windows* OS, open the command prompt as an administrator and run the amplxe-sepreg.exe utility located at <install-dir>/bin64.

To make sure your system meets all the requirements necessary for the hardware event-based sampling collection, enter:

amplxe-sepreg.exe -c

This command performs the following dependency checks required to install the sampling driver:

  • platform, architecture, and OS environment

  • availability of the sampling driver binaries: sepdrv4_x.sys, socperf2_x.sys, and sepdal.sys

  • administrative privileges

  • 32/64-bit installation

To check whether the sampling driver is loaded, enter:

amplxe-sepreg.exe -s

If the sampling driver is not installed but the system is supported by the VTune Profiler, execute the following command with the administrative privileges to install the driver:

amplxe-sepreg.exe -i
