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

SYMPTOMS
When you start a computer that is running Microsoft Windows XP with Service Pack 2, the Realtek HD Audio Control Panel may not start. Additionally, you may receive the following error message:
Rthdcpl.exe - Illegal System DLL Relocation

The system DLL user32.dll was relocated in memory. The application will not run properly. The relocation occurred 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.
This problem occurs when the Realtek HD Audio Control Panel (Rthdcpl.exe) by Realtek Semiconductor Corporation is installed.
