Yes, a patch for a patch: 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.
This problem may occur after you install security update 925902 (MS07-017) and security update 928843 (MS07-008). The Hhctrl.ocx file that is included in security update 928843 and the User32.dll file that is included in security update 925902 have conflicting base addresses. This problem occurs if the program loads the Hhctrl.ocx file before it loads the User32.dll file.
