This article describes how to manually remove VSE 8.8 if automatic removal is not an option or fails.

IMPORTANT: Use the following instructions only as a last resort for removing VSE 8.8. Before attempting a manual removal, try all other methods first.

  • The following information is intended for System Administrators. Registry modifications are irreversible and could cause system failure if done incorrectly.
  • Before proceeding, Intel Security strongly recommends backing up your registry and understanding the restore process. For more information, see: http://support.microsoft.com/kb/256986.
  • Do not run a .REG file that is not confirmed to be a genuine registry import file.

Use one of the following solutions that best fits your requirements:

Use msiexec.exe to remove remnants (if Add/Remove Programs is unavailable)

Sometimes you can remove VSE remnants using msiexec.exe with the product installation string. This method saves time, and Intel Security recommends that you use this method before you try to manually remove VSE using any of the remaining solutions.

Use this solution if you plan to re-install VSE 8.8
This solution is not applicable if SYSCore 15.3 or later drivers are present. Check the version of the file %windir%\System32\Drivers\MFEHIDK.SYS before continuing.

This solution is intended to be used when the product is failing due to existing registry/file/folder corruptionan and the administrator wants to perform a manual removal and re-installation.

  • This procedure relies on the assumption that Access Protection can either be disabled, or is non-functional on the system. The following information is all that is necessary to remove registry/file corruption for VSE only, and perform a clean install.
  • Ensure there is no other McAfee software installed on the system. This includes removing the McAfee Agent. Performing this procedure can also remove drivers shared by Host Intrusion Prevention.
  1. Click Start, Run, type regedit, and then click OK.
  2. Navigate to HKLM\System\CurrentControlSet\Services, and delete the following Keys:

    NOTE: Perform this step for the McAfee services listed under the additional CurrentControlSet0#\Services keys as well, if they exist.

    (NOTE: Possibly appears as mfetdik.sys, or mfetdi2k.sys, depending on whether the operating system is 32-bit or 64-bit)
  3. Navigate to the appropriate location and delete the McAfee key:
    32-bit systems: HKLM\Software
    64-bit systems: HKLM\Software\Wow6432Node 
  4. In Windows Explorer, navigate to one of the following locations and delete the McAfee folder:
    32-bit systems: C:\Program Files
    64-bit systems: C:\Program files (x86)
    32-bit systems: C:\Program Files\Common Files (if it exists)
    64-bit systems: C:\Program Files (x86)\Common Files
  5. Navigate to C:\Windows\System32\drivers and  delete the following files:
    IMPORTANT:  Delete only the listed drivers. In certain scenarios, there could be non-McAfee drivers that start with mfe*, and deleting those drivers could cause unwanted system changes.

  6. Navigate to C:\Windows\System 32 and delete mfevtps.exe.
  7. Restart the system and attempt a new local installation.
