Carey,
Thanks but I'm not sure how your reply relates to my question. I already
have "Windows Installer. V 4.5.6001.22162" installed. What I need to
know is how to remove a specific version of a DLL from the Windows
Side-by-Side folder (%windidr%\winsxs).

I wouldn't take any notice of Carey - he's a clown and techno-retard!

I [quite satisfyingly] solved a problem on my dad's laptop this morning that
was coincidentally much like this one. There was an svchost.exe process
maxing out the CPU, making the laptop very slow to use. Using Process
Explorer I found that it was a wuaueng.dll thread that was causing it.
There were two different versions of wuaueng.dll on the system. After doing
a bit of Google research I found I had to stop the wuauserv service before I
could delete the containing folder for the older file (which, strangely, had
a more recent version number).

Find out what has a handle on your MFC80U.dll file. Unless you have Process
Explorer already in a folder added to your PATH, from an elevated command
line type:

\\live.sysinternals.com\tools\procexp.exe

Then in Process Explorer > Find menu > Find handle or .dll > type MFC80U.dll

See what service(s) that the process that is using your .dll is using.

I do not have Vista to hand, so I cannot check myself. MFC80U.dll is only
being used by a NOD32 process on my XP laptop here. Google searching
suggests a couple of likely services (one of which was the same in my
problem).

net stop wuauserv

net stop cryptsvc

del %windir%\winsxs\MFC80U.dll (or wherever it is)

net start wuauserv

net start cryptsvc

ss.
