IE "performed an illegal operation and will shut down"

by huxley / December 13, 2004 9:13 PM PST

Using Windows 98SE and IE version that came with the computer (bought in Oct '99). The only new software loaded prior to this happening was going to a wireless broadband connection. Computer mainly used for browsing and e-mail through Compuserve, and storage of photos (which was been done well before current problems)

I think I may give up on IE and go to Firefox etc. but in case there is a simple fix.....

I receive the following error message in Explorer:

"This program has performed an illegal operation and will be shut down. If the problem persists contact the program vendor".

If I click on the Details button I get the following:

"Explorer caused an invalid page fault in module MSVCRT.DLL at 017F:780154A7 Registers: EAX=7803A152 CS=017FEIP=780154A7 EFLGS=00010212 EBX=00000010 SS=0187 ESP=0145c754 EBP+0145c764 ECX=0fffffff ES=0187 EDI=0145c79e GS=0000 bytes at CS:EIP: 66 8b 04 48 a8 04 74 5b 83 cl d0 3b cb 73 7b 83 stack dump: 0145c808 70a9f33b 00000000 00000000 0145c7c0 7801540c 0145c79c 00000000 0000000f 00000000 63713aa9 0145c79c 00000000 00000010 00000001 63713c10"

On closing this error box I then get another with the

"An error has occurred in Internet Explorer. Internet
Explorer will now close. If you continue to experience
problems please restart your computer".

This has been occuring for some time but lately has become more frequent. It seems to occur in certain websites (eg e- mail) more often than other

I have tried Stinger, CWShredder, Ad-Aware, SpyBot etc. And I have read several pages of posts already and there are some similar problems as mine but nothing is described as exactly like mine.

Any help appreciated,

I had the same problems and they seemed to go away for the most part once I went to firefox. I occasionally get a fatal error still. I think it has something to do with drivers loaded on your machine. My problems started once I download microsofts new security pack - it seemed to cause more problems than anything else!

Thanks Mark.

And you reminded me that the only other new stuff on my computer are new security packs from Microsoft!

I'm going to give Firefox a go!

Invalid page fault in module msvcrt.dll
by Cursorcowboy / December 14, 2004 8:26 PM PST

1. When a "<program>" error concerning Msvcrt.dll appears to be caused by a recently installed application -- or maybe not so recent, uninstall this program and reinstall. You could perhaps search the Microsoft library by entering the following search parameter in the box labeled, This exact phrase:, and then press Enter. It may be to your advantage to indicate the OS on the top line.

Invalid page fault in module msvcrt.dll

2. The article [Q315854] provides a single resource for information about the most commonly reported error messages in Win98, Win98SE, and WinME. When you click one of the links contained in this article, and based on your operating system and error message, a list of the Microsoft Knowledge Base articles that are available for that error appears from which you can then select the article that applies to your issue.

3. The article [Q302756] states that when you attempt to start Windows, you may receive an error message similar to the following that may be caused by a damaged Msvcrt.dll file which you will have to extract a copy from your Windows media:

C:\Windows\System\Msvcrt.dll is corrupt

This program has performed an illegal operation and will be shut down.

If the problem persists, contact the program vendor.

? If you click the Details button, the following information is displayed:

EXPLORER caused an invalid page fault in module EXPLORER.EXE at 0167:address

? You may then be unable to start Windows.

program has performed an illegal operation
by cesarp / December 19, 2004 5:52 AM PST

I have the same problem and a similar question. In my Win 98 SE several applications (IE, Netscape, DOS tracert, msipcfg, etc) ran into the same error mesassage ONLY WHEN I HAVE a DSL cable or a network card plugged in. I use ConfigSafe to return to a good system (properties and configuration, etc). I have deleted and wipped clean my registry entries for Netscape and IE and re-intalled them ... but in vain. I have also swapped RAM memory in hopes to clear page faults due to bad memory spots. I can configure and use a network with my other units (Win 2000 and XP) but not with my Win 98 SE Aptiva (IBM 2170-802). In my win 98, when restored, EVERYTHING WORKS without NETWORK OR DSL configurations. Does any one have any root cause ideas or suggfestions of how to fix a WIN 98 network problem? - Cesar
