VirusScan 8.7i Patch removal

I found in the release notes for VSE 8.7i Patch 5 the following concerning removal of patches:

Removing the installation

Windows Installer 3.x and later now support the rolling back of Patches. This can be done one of two ways.

For Windows XP, Windows 2003, Windows Vista, Windows 2008, and Windows 7 operating systems, the Patch can be removed

manually via Add/Remove Programs if the user has administrative rights to the local system.

For all operating systems that support Windows Installer 3.x, a command-line option can be used to remove the Patch silently.

Example: C:\WINDOWS\system32\Msiexec.exe /I {147BCE03-C0F1-4C9F-8157-6A89B6D2D973} MSIPATCHREMOVE={B19278AD-EFEF-

4C8A-8E37-7000DA63C029} /q

Patch removal considerations

The GUID information used here changes from one Patch to another. Always use the information in the Release Notes for the

Patch that you are removing.

Because the Patch is removed via MSIEXEC, the functions inside setup.exe, which normally prevent reboots from occurring

during silent processes, are not executed. In order to prevent a possible automatic reboot from occurring after a Patch removal,

simply add the REBOOT=R parameter to the command-line option above.

Patch removal is an MSI reinstall function. When a Patch is removed, all features affected by the Patch are reset to installation

defaults. Any features not modified by the Patch are left with their current settings.

Update VirusScan Enterprise after removing the Patch to ensure that the latest versions of the engine and DAT files are running.


But this is missing in the VSE 8.7i Patch 5 repost release notes. Does this process still work to remove Patch 5 from VSE 8.7i? Thanks in advance.
