Windows 7: MSE Update KB2754296

Last night I was notified that new updates were availible. I went to the update page and selected all of the important updates.

KB2754296 failed to installed. I have tried several times to get it to install.



During the attempt to install the update I get this message:



After a few seconds the top two (2) parts of that message go away. Then I get this:



MSE seems to be working normally but I can NOT figure out why this update keeps failing. Any suggestions would be helpful.

BTW is there any place I can download this update and install manually?

Thanks

You're the lucky one!
I installed an update to the MSE ongoing Beta this morning, and it took me two hours to get back into my system again.
(seems like no damage done, and MSE updated definitions properly afterwards but....)

Usually, the easiest way around MSE update errors is to uninstall and reinstall.

I had similar problems. It looks for a file epp.msi but it appears it has trouble finding it, the file is in the Backup folder or MS Security Client but in the AMD64 folder.

I found epp.msi in:

C:\Program Files\Microsoft Security Client\Backup\x86

Where should it be ??

On a Win 7 64 Bit system i found epp.msi in \Program Files\Microsoft Security Client\Backup\amd64
On a Win 7 32 Bit system i don't find epp.msi

The MSE update worked on both of these systems.

I found epp.msi in this log (Win 7 64 Bit)
\ProgramData\Microsoft\Microsoft Security Client\Support\MSSecurityClient_Setup_4.1.522.0_epp_Upgrade.log

See if you have this log file and if it shows any errors.

I was mistaken, the 32 Bit system i looked at does not have MSE on it.

I just checked a 32 Bit system with MSE and the file is:
\Program Files\Microsoft Security Client\Backup\x86\epp.msi

I got all these on Tuesday night and had no problems with the installs.

At the moment I have NO clue why the update is NOT working. As long as MSE continues to work in a way I think it should, I will leave it alone.

If MSE should stop working then I will uninstall it and then reinstall the latest version.

Right now I can't think of anything else to try.

I am getting the same failure to install update. It also crashes MSE. Had to do a system restore and hide the update.
