Problem

When installing McAfee VirusScan 8.7i you may receive an error that says:

This installation cannot continue until the ePO Management Agent is of version 3.6 or higher.

Solution

To resolve this problem you must remove McAfee ePolicy Orchestrator (ePO) from your computer.

1. Click Start > Control Panel.
2. Double-click Add or Remove Programs.
3. Locate McAfee ePolicy Orchestrator and click Remove to uninstall it.
4. If you get an error when trying to remove ePO or if it is not listed in Add or Remove programs, you must manually remove ePO from your computer. Refer to 1209: How to manually remove McAfee ePolicy Orchestrator (ePO).

Once you have removed McAfee ePO, you may install McAfee VirusScan 8.7i.

Alternate Solution

Before considering this alternate solution, try removing McAfee ePO from your computer as described above. As a last resort, refer to the information below.

The error described above indicates that the McAfee VirusScan installer is detecting McAfee ePO on the computer. If you have been unsuccessful in removing McAfee ePO from your computer, you should locate and remove any extraneous McAfee or Network Associates registry keys on your computer.

Important!
Editing the Windows registry incorrectly can cause serious problems to the operating system. These problems may prevent Windows from booting properly and may result in data loss. It is highly recommended that you make backups prior to making changes to the registry. Refer to 1115: Backing up and restoring registry keys in Windows.

To remove extraneous McAfee or Network Associates registry keys, do the following:

1. Make a backup of your registry before you begin. Proceed with these instructions only if you are confident about what you are doing.
2. Click Start > Run.
3. Type regedit and press Enter. This will open Registry Editor.
4. Double-click HKEY_LOCAL_MACHINE > SOFTWARE.
5. Locate the McAfee registry key and the Network Associates registry key. You may have one or both of these.
6. Expand the McAfee and Network Associates registry keys to inspect their contents and sub-keys. If you have McAfee or Network Associates software installed on your computer apart from McAfee VirusScan and McAfee ePO, then you should use caution when considering whether or not you want to delete these registry keys. If you delete these registry keys, you may find that other McAfee or Network Associates software no longer functions as expected. If you are sure that you do not have any additional McAfee or Network Associates software installed, delete the McAfee registry key and the Network Associates registry key.

Once you have deleted these registry keys, you should be able to install McAfee VirusScan 8.7i.
