RTHDCPL.EXE Illegal System DLL Relocation

I just installed an auto-upgrade to a windows xp professional machine. I
receive the following message.

The system DLL user32.dll was relocated in memory. The application will not
run properly. The relocation occurred because the DLL
D:\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.

1. how do I find out who the vendor is?
2. how can I fix this problem.

Hi Sherrie51,

Have a look at this MSKB article:

The Realtek HD Audio Control Panel may not start, and you receive an error
message when you start the computer: "Illegal System DLL Relocation"

Thanks very much Patti. I too, had this problem and had come into the group
to see if anyone knew what it meant and what I could do to resolve it, so I
was very pleased to see your reply to Sherrie.

I just want to say though that I think it's shameful that Microsoft make you
go through the Windows Genuine Advantage routine first before you can get
the fix for the problem. I don't condone piracy in any way and I only use
genuine software, but sometimes people can be running non-genuine software
without even being aware of it, and I think it's deplorable that the "fix"
for a "fix" is only available to genuine software users.

If someone's system was working before the "security update" but not after,
then I see it as being Microsoft's update that broke the system, and the fix
required to make it work properly again should be available to *any*
affected system, genuine or not.

Thanks again,

John.
