Question about Computers & Internet
Error Message after Installing Security Updates 925902 and 928843 This afternoon (April 3rd, 2007) my Automatic Updates alerted me about a couple updates I needed to install, so I did. Upon rebooting the computer though I was confronted with 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."
Cause of Error Message
Turns out this error occurs when the Realtek HD Audio Control Panel by Realtek Semiconductor Corporation is installed. This is my built-in sound card on my computer.
The HHCTRL.OCX file that is included in the Security update 928843 and the User32.dll files that is included in Security Update 925902 have conflicting base addresses. When Windows loaded the HHCTRL.OCX file before it loads the User32.DLL file, the problem occurs.
The error occurs when the following third party programs or applications are installed on a computer with Windows XP Service Pack 2 installed.
Realtek HD Audio Control Panel
