RTHDCPL.EXE - Illegal System DLL Relocation

Hi there.
I am a XP Professional user and recently the following message appears at
the startup of my PC:
RTHDCPL.EXE - Illegal System DLL Relocation
The System DLL user32.dll was relocated in memory. The application will not
run properly. The relocation occured 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.

How can I solve this?
Help please.

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

There should be a downloadable fix available now...this was just discovered
in the past day or two...

My computers at home all had a critical update with mandatory reboot during
the night, so maybe this fix went out...

Dear Dana et al,
Result of the April 3 update. No doubt about it. (XPmc 2005)

ok i am having this same problem where can i go to find the download fix??

HOORAH!!!!!! Found the fix and it works for me. If you use the hyperlink
below (copy & paste into your browser) you can download the fix.

Hi everyone,

I'm having a similar problem that started just today:

On startup, a service called quickstart.exe brings up the Illegal System DLL
Relocation, with user32.dll and system32.dll mentioned.

I've also been using File Manager carried over from Windows NT on my XP Pro
Service Pack 2 machine, and it too is affected by the problem - neither
quickstart.exe nor winfile.exe will start.

I traced the problem to an errant Windows Update, the rolling back from
which, via System Restore, causes the problem to go away. A System Restore
Point created at 3:00 AM today mentions "Software Distribution Service 2.0"
which from a Google search, appears to have a history of problems.

Problem is, with Autmatic Updates in the equation, the unwanted update comes
back into play very quickly. I've turned off Auto updates but the Update has
been redownloaded and is on the queue to be installed on Turn Off.

Obviously I don't want to allow that - could someone tell me how to kill
downloaded updates?

Is there anything else I can do to make sure this problem doesn't come back?

I'm wondering what to do now after running the hotfix. Is the fix a
replacement for the bad upgrade or is it a prep for receiving the upgrade
correctly into my system.

The Hot Fix worked but as mentioned here, I am still showing the upgrade
icon in my systray. Do I click on it again after installing the hotfix?

I too am having this problem. It seems from the previous answers that a roll
back will work, but that seems to be a bandaid, not a fix. Any suggestions
which will allow updates but avoid problems????

I agree that a restore solves the immediate problem - but then soon after the
automatic update resets the problem again. Why aren't more people
experienceing the same problem?? More importantly - what is the fix?

I'm also having this problem. It's definately the latest upgrade, it helped
for 10 minutews before Windows Updated and after the reboot the error was
immediately back.

I had the same problem too - happened after the upgrade. I have not done
anything to fix this yet - there does not seem to be a permanent fix.

I'm new to computers. Do I not simply wait for a patch which will come out
in the next upgrade? I would think that this should come out soon because
everyone is experiencing the same problem.

I have same problem, just started. I don't think I had an upgrade download.
I had laptop off, turned on and get the ILlegal system dll relocation error
like everyone else. what is causing it and how do we fix it?

MS should TEST their updates before adding them to the automatic updates.
It's ridiculous to have to fix a problem that was created by microsoft.

I have same issue with my Sony Vaio laptop after automatically upgraded. I'm
wonder is that part of the upgrade which it checked out the system and them
it tell you that your system is availuable to upgrade to Windows Vista, then
after all, it caused this kind of problem? Do you All have this kind of
upgrade? Please Help.

OK we all have the same problem. What is the fix for it? I didn't download
anything so it must be an automatic upgrade that caused this. VIAO system
with XP. Who is hte vendor supplier?

I'm strongly believe that comes from Windows upgrade issue, I hope they can
find out what really caused the problem and fix it for All of us. thank you
very much.
