Windows Application Error

Last Modified: 2010-03-05
When I exit some applications I continue to get this error
message. (The name of the app and the memory addresses are
different in each case hower the message is the same)
Any and all help is appreciated.

Application popup: IEXPLORE.EXE - Application Error : The
instruction at "0x02c9dc39" referenced memory
at "0x00000ba0". The memory could not be "read".

Click on OK to terminate the program

Run System File Checker to restore and repair all Windows files:

Start » Run » Type "sfc /scannow" without the quotes. There's a space before the /.
Click OK.
Have your Windows CD ready to insert if prompted when repair is necessary.

The problem is covered in detail here:

Here is a shorter version:

Update and run all AV & antispyware.

Make sure all Windows Updates are installed.

Run defrag.

If SFC doesn't fix the problem:

Repair installation of Windows.

This leaves all your programs and data intact while reinstalling Windows.

1.  Boot the computer from your XP CD.
2   When you see the "Welcome To Setup" screen, Press Enter to start Windows Setup.
3.  Be careful NOT to choose R - "To repair a Windows XP installation using the Recovery Console".
4.  Accept the License Agreement.
5.  Windows setup will search for existing Windows installations.
6.  Select the XP installation you want to repair (probably only one) and press R to start the repair.

More complete instructions on how to do this, complete with pictures, are here:

Back up your data first, just in case!

One more thing nikosmas:

Do you have adequate Antispyware?
In addition to Windows built in Defender (if you're using IE7) you need:

Ad-Aware (there's a free personal version)

Spybot (free!)


AVG Anti-Spyware (free for home use)


SUPERAntispyware (free for home use)

Hope this helps.

Also, try Dial-a-fix (http://djlizard.net/software/Dial-a-fix-v0.60.0.24.zip). Check all checkboxes under the "Registration center", section and click "GO".

If none of these suggestions helps, you might try testing your ram.  Use memtest86, you can get it here: : http://www.memtest86.com/
Hope this is helpful,

Um, suggestion... even though we're not sure if it answered this persons question... there is a lot of good info here, especially Vallis comment.
