Error with MFC42u.DLL file

I am receiving the following error message when starting iTunes, "This application has failed to start because MFC42u.DLL was not found. Re-installing the application may fix this problem." I have downloaded the most recent vrsion of iTunes but the error remains. If I do a file search I see that I have several files with that name in different directories and with different dates for when last modified. I am also running Windows XP. Anyone have any suggested fix?

I am always a bit nervous about dlls.

On my system, iTunes looks for MFC42u.DLL in c:\Program Files\iTunes first, but it isn't there, then it looks in c:\Windows\system32 where it finds it. I have copies in other locations to.

So, do you have a copy of MFC42u.DLL in your system32 folder?

Is it in the %windir%\System32 folder?

Thank you for the posts. I ended up working with the PC manufacturer, HP, on the solution which was as follows. HP was very helpful in assisting with the fix and it turned out to be very simple (same as the posts suggested).

Remove the current iTunes application through the windows control panel
Go to the following url and download the updated dll into the C:\Windows\System32 folder: http://www.dll-files.com/dllindex/dll-files.shtml?mfc42u
Reinstall the iTunes application from the iTunes web site

Of course when I posted a question to microsoft they said the windows application was not at fault and to work with the manufacturer. I should have known they would not be willing to help.

Thanks again for the posts.
