Cannot uninstall Mcafee EPO 4

We have switched Av vendors from Mcafee to Sophos, so I wish to remove the EPO program from our server.  When I use add/remove programs I get this error message:

The installation source for this product is not available.  Verify the source exists and that you can access it. C:\windows\installer\22e51555.msi

As the file in question not on the server, I used the original install package to remove EPO (ran the setup.exe) and I am presented with a nice Mcafee window which states it's going to remove the program from my system.  I select the EPO database as well as I no longer require it and click on Remove.  The program twice asks me if I'm sure, then a screen appears with a progress bar which looks like EPO is being removed,(The Installshield Wizard is removing EPO).  The screen then vanishes after 30 seconds or so without doing anything.

I have tried using the MCPR.exe removal tool from Mcafee, but the program just wont go!  Any idea how I can get rid of this and the Mcafee Agent program from my server please?  The server is Windows SBS 2003, if that helps.

Hi Juddy,

I understand that you are unable to uninstall the EPO 4 version which was previously installed using the original install package.

I would suggest that you should try to manually remove McAfee ePolicy Orchestrator (ePO) from your computer. Please visit the link below in order to follow these instructions.Remove McAfee ePolicy Orchestrator:


Hope this helps in uninstalling the EPO 4 from the server.

 If the above does not work then you may manually deleted all the files and clean out the registry.

Acouple of things:

We were using Mcafee 3.7i

I don't have a c:\programfiles\mcafee\common framework folder

I tried this method:

1.    Click Start > Run.

2.    Type cmd and press Enter.

3.    Type cd\ and press Enter.

4.    Type cd program files and press Enter.

5.    Type cd network associates and press Enter.

6.    Type cd common framework and press Enter.

7.    Type frminst /remove=agent and press Enter.

The Mcafee Agent installer/uninstaller window appears, the progress bar moves across and then I get the following message:

Mcafee Agent setup completed sucessfully.

This seemed to remove Mcafee Agent, but EPO is still there!! Any suggestions?

Hi Juddy,

Thanks for the update, as you mentioned that you still see the EPO can you tell me the path and also let me know if you tried deleting the folder and epo entries from registry manually, you may try in the safe mode.

I managed to speak to Mcafee, they gave me atemporary Grant Number even though our support has expired.  I used the Microsoft Clean Up Utility to remove EPO from here:


Which seemed to be doing quite a lot, allthough EPO still appears in add/remove programs but with no file size.  I cannot reboot the server until tomorrow, as it is also our mail server but I must complete the following steps to finish:

Reboot the server

Then after reboot

Delete following keys

[HKEY_LOCAL_MACHINE\SOFTWARE\Network Associates] [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{66C69D80-C95C-11d3-8A0B-006008C7D0F2}]

Delete the ePO installation folder. This is located in the following folder by default:  C:\Program Files\McAfee\ePolicy Orchestrator

This process does not remove any instances of SQL that are present on the server or any ePO databases that may be attached to an SQL instance. Do the following to remove these:

Determine the ePO database name:
Click Start, Run, type explorer and click OK.
Navigate to:  c:\Program files\McAfee\ePolicy Orchestrator\Server\Conf\Orion\db.properties
Right-click the db.properties file and open in Notepad.

db.database.name indicates the ePO database.
db.server.name indicates the SQL server name.

The ePO 4.0 database is typically named EPO4_<servername>.

NOTE: For a named instance, the db.instance.name value is populated. For a default instance, db.instance.name is blank.
Using this information, the ePO database can be safely dropped using tools such as SQL Server Management Studio or SQL Server Enterprise Manager by connecting to the correct SQL Server instance.

I will do this on Thursday morning and post my results here.

Using the Microsoft clean-up utility, removing the registry entries (as per my last post) and running CCleaner (on the file system and the registry) I have finally removed EPO!!
