everytime I open my laptop, a pop up says that mpclient.dll is missing from my computer and I need to reinstall the program so that it will work.  I was trying to install Microsoft security essentials, but it will not allow me to do it because of some Microsoft security client issue.  I have no idea what is going on.

Try reinstalling the Windows Defender program; if the problem is not solved, check the program directory for mpclient.dll by going to Search, All Files and Folders, More Advanced Options and selecting Search Hidden Files and Folders. If the file is not available in the program directory, you will need to download it either directly from Microsoft or from a reliable third party web source.

 

edit: to manually replace it if no go on the reinstall... dl it first from a safe place or copy it off another machine, then

 

  1. Save MpClient.dll to C:WindowsSystem32winsxsamd64_security-malware-windows-defender_31bf3856ad364e35_6.1.7600.16385_none_b3b1a27171e01f6c
  2. Type regsvr32 MpClient.dll and press Enter in CMD window

none of this has helped me.  I have tried everything on my computer.  I tried reinstalling it, but it will not reinstall.

So you downloaded the dll file and placed it in place, executed it... and it still can't find it?

 

Might be time to run "sfc /scannow" from an elevated command prompt.

 

If that doesn't work do a repair installation from either the harddrive (if it has a recovery partition), by pressing f8 at boot, or from disk.

ok... well if you can't do it manually, you have to use the auto procedures outlined above.

 

Let us know how you get on.
