View Full Version : Load to Desktop Error Messages

Hi everyone. I hope I posted in the correct location. I have a question about an error message when I boot up to the desktop.

I have a HP Pavilion, P4 3.66, 448 MB Ram running Windows XP Media Center Edition SP2. When I first boot up and after the desktop has pretty much loaded, I get the following error message in a dialogue box -

RTHDCPL.EXE - Illegal System DLL Relocation  At the top of the dialogue box

“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”

I can click the “ok” on the dialogue box and continue on without incident and this error doesn’t seem to hinder my machines performance, so I dunno. It MUST the affecting something, right? My first thought is hardware or something, but when I look at my device manager, all is a-okay – No yellow exclamations, etc.

Is there a way to determine what this is so I can correct it. Started happening about a month ago sporadic like, but now it’s every single time I boot.

Any help you can provide would be most appreciated.


Oh. I almost forgot. Not sure if this is related or not, but see my other post here, http://www.pcguide.com/vb/showthread.php?p=342540#post342540

Certain third-party applications may not start, and you receive an error message when you start the computer: "Illegal System DLL Relocation" (http://support.microsoft.com/kb/935448).
