Hi all, I get a serious problem after installing SP2.

An error msg poped up when I right click any file in my documents:

explorer.exe - Application Error

The instruction at "0x0271415b" referenced memory at "0x00000000". The memory could not be "written".

Click on OK to terminate the program

Click on CANCEL to debug the program

Could anyone tell me what happen and how to solve this??

Thanks all.

Are you running it in a virtual machine? If so, you might need to increase the RAM on it. Or, if your running it in a computer with low RAM you might get that message as well. Can you bring up the task manager and tell us how much RAM is in the system and what the PF usage is?

Here is the Task attached.

I am running in a computer, not in the virrual machine.

This problem didn't occur before installing SP2.

Oh...come on...everyone....please don't let this topic stop here without the solution.

Sometimes context menu handlers\shell extensions will cause this problem.

Try this Program:

I'd focus on 3rd party application Shell extensions.

Try disabling one and see if that stops the crashes. If not, try disabling another until the problem goes away.

Does it happen on any file type or certain file types?

if you have divx installed, uninstall it. problem should be fixed

Do you have Spysweeper 3.0 installed? This was causing problems for me. They have released a new build that fixes this.

I had same problem (applicatione error). Occured on all systems with DIVX and SP2 installed. Clue should have been REGSVR32 error during DIVX install. Uninstalling corrected problem.

I have the same problem it only happens when i right-click anything that is not a folder or a shortcut to a folder. I have installed SP2.. but it seemed to work for a few days. then last night is when the error started.

So, thats mean i need to uninstall DivX if I want to install SP2?

But, I need DivX to watch most of my movies.

It seem failed to install this program in my pc.

My problem occurs for every files.

I'm having the same problem too

I thought it was because of DivX 5.2, now that i uninstalled it and reinstalled DivX 5.1 the computer worked just fine but just for a while. Now it does it on its own, sometimes i get the error, sometimes i dont.

It's a real annoying thing hope someone has a real fix for this problem

Man, this is really odd, I have divx V5.2 in my computer and have had no trouble with any of this at all.

I feel neglected, my computer has been running sp2 for nearly two weeks now and I have not had any of the problems that others have had. However, I am greatful for that also. As I said in another thread, I have upgraded quite a few computers already and have not had a problem with any one of them.

what bothers me is, I know eventually I will have problems somewhere down the line with some customers computers, it is bound to show up sooner or later, but what I do not understand is why some have alot of trouble and others like myself have little or none.

Must be Microsoft slipped in a secret code to hate some computers and love others, does make one wonder...

I had the same problem opening DIVX and XVID, some muppets on other forums are running mem test.

A quick work around that works for me is to cut the containing folder and paste it somewhere else. then open up you DIVX file and it shouldn't crash explorer.

don't ask me why it just works for my machine.

I had this same problem on my laptop. Very irritating. I followed the helpful post instructions on http://www.mcse.ms/archive64-2004-8-945860.html This fixed my problem. THANK YOU Mike!!!

The short text of his post is:

Check if those PC have DivX codec installed. If so, go to the following in

"regedit" & remove the "DivX" entry:

[HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers]
