RTHDCPL.EXE - Illegal System DLL Relocation

  Jeecie 21:20 04 Apr 2007

"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\HHCRTL.OCX occupied an address range reserved for Windows systems DLLs. The vendor supplying the DLL should be contacted for a new DLL."

I updated Windows XP Home Edition SP2 last night and when I re-booted the laptop this morning I got the above error message pop up.

After some searching around I found Microsoft have published click here (Article no. 935488) a hotfix for it which can be downloaded (click here).

I thought I'd post it here in case anyone else has the same problem!

Best wishes
Jeecie :)

Thanks to all concerned with this fix, I too had a Windows Update last night which stopped one of my programmes from working. All is well now.

All it mentions is:

"Install this update to resolve an issue where the Realtek HD Audio Control Panel may not start after you install security update KB925902 (MS07-017) and security update KB928843 (MS07-008).

Not clear how this relates to RTHDCPL.EXE. What's the connection?

RTHDCPL.EXE is the file that loads the sound card driver at start up. RT=RealTek HD=High Definition CPL=ControlPaneL. EXE=Execute.

Hope this helps

I've also had the same problem tonight. All appears OK now.

Thanks Jeecie for the fix.

Thanks Jeecie, I too have the same problem, I will now run the fix and see if it sorts the problem. Thanks again.

It worked for a few hours. But the fault is back !! I switched on the PC today and it came back. What seems to happen is that it AUTOMATICALLY "updates" the security options when I restart the PC. So it keeps on putting this thing in there. How can I prevent this particular "update" from automatically occurring?
