Getting This Error

I tried to install Norton Utilities and got the following error.  When I run a registry cleaner I get all error, then when I ask to fix I get the same error after few seconds.  What is this error about and how to fix it?

This is the error:

The instruction at "0x0041d15c" referenced memory at "0xffffffff", the memory could not be "written".

Click OK to terminate the program
Click on CANCEL to debug the program

When I press OK the program terminate.

When I press OK I get:
RegCleanExpert.exe has generated errors and will be closed by Windows.

Thanks a lot

Problem could be Bad RAM

Test it using 

try using other RAM, if you have 2 RAM, then take 1 out and confirm it. OR you can test it here
download the program

Try using Boundchecker or the less expensive Memcheck (a 14 day trial version is available at Both of these tools do a good job in determining various errors (see for a complete list)

You have not provided nearly enough information about your problem.  What version of Windows are you running?  What version of NSW?  Do you have other Norton products on your system already?  If so, uninstall them, reboot, then run Regedit.exe from Start/Run and remove any Symantec registry keys from the registry.

Do other programs crash on you?  If not, then your RAM is likely fine.  Have you tried contacting Symantec support about this??

shivsa, is apparently offline, FYI.

Also...9 times out of 10, these "memory could not be read/written" errors have nothing at all to do with truly faulty memory; its usually a bad .dll file causing problems or possibly a virus/malware program.  Have you checked your system for virii?  Http:// is a good resource for running a free online viruschecker.  You may even be able to boot your PC from the NSW CD depending on what version it is (the retail version of NSW 2004 does this, as does NAV 2004) and run a virus check that way (though the virus definitions it has are fairly outdated)

Also check for malware/spyware/adware using AdAware:, download AdAware Personal 6.181.

Hi dogztar,

I downloaded the simm tested and started it,  it worked more than 14 continuous ours without finishing and without finding an error.  I am inclined to your suggestion, because I have this problem after uninstalling ICQ.  When I use registry cleaners I get this problem after errors are found.  It might be what is called DLL hell or a virus.

I have Adaware 6.181,  it does not find any problem.

I used Norton but it did not find anything,  I update Norton's  definitions daily

I will try scanning and will let you know.

Try download HijackThis from
Run it, click Scan, then Save Log, then copy/paste the content of that log file here.

Kyle SchroederEndpoint EngineerCommented:
Is your Adaware up to date?

Hi Dogztar

I finished scanning,  the scanner you gave me above found one trojan called:
Startad  I deleted it.

I have a program called ExpertCleaner,  it scans the registry and cleans bad lines.  When I finish scanning I get 65 errot in the Windows Startup Items. When I try to fix the problems I get this error.

I have Hijak This,  I will try it and let you know.

Kyle SchroederEndpoint EngineerCommented:
65 errors in WIndows startup items?  Yeesh...does it provide a method to save/export the results?  I'd like to see what it thinks was missing...

hhammashAuthor Commented:

I updated AdAware definitions and it found many spy programs 3 of them are called Malware.  I deleted all of them,  restarted the Computer and tried to clean the registry using ExpertCleaner. When it prompted to fix the problems,  I clicked Fix, then I got the error again.

Do you know about any good professional Registry Cleaner.

I also use a program called ..Utilities2003,  I don't remember the full name now.  It scans the registry and finds the problems,  then cleans them without getting the error.

Is it possible that the other program is creating the error?

I tried to reinstall ICQ,  I got the error
I tried to install Norton AV 2004 and got the error
I installed other software and got no problems,  I did not get the error.

Thank you for your help and patience.

I think whatever this "Expert Cleaner" program is, it is corrupting your registry which is why you're getting this error.  Please don't use it, for your PC's health.  Norton Utilities (now, Norton SystemWorks) does have a registry cleaner program, its called "WinDoctor".  But clearly that is what you're trying to install (you said Norton Utilities, what version of Windows are yo using?  Clearly 2000 or XP (or NT4)...if you're using the old Norton Utilities, they are not compatible with Windows 2000 or XP.

Have you tried reinstalling the current service pack on the system (SP4 for Win2K, SP1 for XP)?
Searching on this error:
Returns over 1,000 hits...its a common problem (I've experienced it several times) but there doesn't seem to be any definite cause or solution, even reformatting/reinstalling Windows doesn't always clear it (which seems indicative of a hardware problem).  Sometimes print driver changes seem to help, sometimes swapping out RAM sticks, removing certain programs...there is really no common theme.  The error is very generic (kind of like "Fatal Exception" in WIn98 or General Protection Fault, same idea).

Try start/run -> sfc /scannow

Also, if you can...change the title of your question, "Getting This Error" is not very informative to someone who might have some input.
u can try any of these registry cleaner and see if it add any help.

How to Install and Run RegClean

RegClean by Microsoft.

Hi dogstar,

I will try to replace the rams with new ones and see.

The registry cleaners did not show any problem,  but I am still getting the error.

Thanks a lot

hhammash:  Try uninstalling all Symantec products from your system, then restart, and remove:
o c:\program files\Common Files\Symantec Shared
o c:\program files\Symantec (or any Norton folders here)
o Registry (regedit.exe): HKey_Local_Machine\Software\Symantec
search for any .dll files on C:\ starting with sym*.dll, if the properties on the Version tab indicate they're Symantec files, remove those too, then restart, and reinstall each Symantec app.

You might also try renaming the <file://C:\Program Files\Uninstall Information> folder and/or "InstallShield Installation Information"
