McAfee Live Safe. Real Time Scanning won't work. Error with dll's when installing.

I recently did a complete factory reset on my Dell N5110 laptop. Running Windows 7 Home Edition, SP1.

For Virus protection etc, I used to use Norton, but this time I thought I'd try McAfee.

So I have installed LiveSafe. However, when it was installing, I had 4 error messages pop up. It did not seem to stop the installation though.

Once installed, the program warned me that 'Real Time Scanning' was not active. Despite attempts to switch it on, it simply would not turn on. I contacted MsAfee support, who were very good, and remotely reinstalled the program, only to see the same error messages, and the same end result. After a bit of investigation, he came back and told me that it looks like it is an issue with Microsoft, not with the McAfee installation software, or LiveSafe.

The four error messages I get are all exactly the same words, the only difference was the title of the dialogue box.

The message is this:

'The procedure entry point Directories could not be located in the dynamic link library KERNEL32.dll'

The title in the dialogue box for each one was: (I can't remember which order they came in)

MCVULA~1.EXE - Entry Point Not Found

MCVULU~1.EXE - Entry Point Not Found

QcShm.exe - Entry Point Not Found

McVulCtr.exe - Entry Point Not Found

Can anyone advise what the problem may be, and how I solve it.

Failing that, if anyone knows where I should perhaps direct this question, to get the best results.

Many thanks,

Stuart.
