Error message - Illegal System DLL Relocation

I am running Windows Vista Home Premium on one drive and Windows XP on the other. When I boot up to Windows XP I am getting the following message:
"RTHDCPL.EXE - Illegal System DLL Relocation.
The system DLL user32.dll was relocated in memory. The application will not run properly. The relocation occured because the DLL C:\WINDOWS\System32\HHCTRL.OCX occupied an address range reserved for Windows system DLLs. The vendor supplying the DLL should be contacted for a new DLL."
When I click OK I have so far not had any further problems but when I reboot into Windows XP the next time the message reappears.
I have no idea who the vendor might be. I have searched for HHCTRL.OCX and found 3 instances of it, two in C:\Windows\Software Distribution\Download|.....
Can I delete these two entries? Otherwise what should I do?
