Hi Guys,

I'm new to the site so I apologize in advanced if this was already posted before. I tried downloading internet explorer 8 and it told me to restart but didn't bother so I just shut it down. The next day as I turned on my computer, there was an error that said "this application has failed to start because iertutil.dll wasn't found"...and the only thing that came up was my wallpaper (i have to find everything through task manager). I've read somewhere that you could try to copy and paste the .dll file in system32...so I did that. After I did that, restarted my computer, another error came up and it said "the ordinal 166 could not be located in the dynamic link library iertutil.dll". I'm guessing it's an internet explorer problem?

Can someone please help me! I have really important files, and I don't want to re-install windows xp. I don't know what to do and I am freaking out! anything is greatly appreciated!

Hello p3tra

First of all try a system restore to before you installed IE8

Boot into Safe Mode Options Screen (the one with Last Known Good Configuration on it) by pressing F8 at bootup and choose
'Safe mode with command prompt'

At the command prompt type
C:\Windows\system32\restore\rstrui.exe

Hopefully this will open System Restore, so restore to before the problem started

Hi Dunedin!

Thanks for the reply. I tried your option but when I entered in the command prompt "c:\windows\system32\restore\rstrui.exe", nothing came up. Also all my restore points are corrupted as I tried to system restore my computer one time before this all happened. =(

OK

Try to uninstall IE8

Open Task Manager
File/ New Task Run and type in
appwiz.cpl
OK

This should open Add/Remove Programs so look for IE8 and try to uninstall it.

You might have to run system file checker.
Again using Task Manager type in
sfc /scannow (there is a space before /)
OK

You will need your XP installation CD for this.

I am having the same issue, right after my computer tried to install ie8 ( I was using the beta with no problems), I keep getting the error message "The 166 ordinal could not be located in the dynamic link library iertutil.dll". I have tried to down load and replace the dll, I have tried to restore my system, but it won't turn on, I have tried reinstalling ie7, all to no avail, I really hope not to have to reinstall xp...

Oh and I did try the system file checker, it did not help.

Dunedin

You have tried to uninstall IE8?

Where did you put iertutil.dll when you downloaded it?
Make sure there is a copy in C:\WINDOWS\system32
And also a copy in C:\WINDOWS\system32\dllcache

I have a more-or-less identical problem - Since an attempted repair of a missing ordinal 160 situation (which was annoying, but not fatal), Windows won't boot properly (no taskbar, icons etc on the desktop) & I'm getting the missing 166 ordinal message. When I boot in safe mode & try to run a system restore from cmd prompt I get the same error message & the restore doesn't run. I have a copy of the iertutil.dll I backed up from when Windows ran OK, but if I try to overwrite (or delete) the current one that's causing the problem from cmd prompt, I get a 'file in use by another process' type message & I can't do that either. Is this a re-install? Will a registry fixer run in this situation &, if so, will it work? Thanks - Dave

Hello DaveSoBlind

It must be Internet Explorer which is using the file?
Try going to Task Manager/Processes and stopping Internet Explorer
Right click iexplore.exe/End Process.

Then try to replace it.

Hi Dunedin,

thanks for the suggestion, but I.E. is not listed in the running processes

Cheers Dave

Dunedin

OK, download and run Process Explorer

See if it will help find iertutil.dll.

DaveSoBlind

Hi Dunedin,

thanks for the suggestion - Process Explorer doesn't find iertutil.dll. Cheers, Dave

Dunedin

Try replacing it in Safe Mode then.

.

DaveSoBlind

Thanks, but I've tried that already & I got a 'file in use' type message. Cheers Dave

Dunedin

I would check for malware then

Hello Karolina

Try downloading IE7 from a different source.
If you got it from Windows Update try downloading it here
OR
Download IE8

Then
Control Panel/Add Remove Programs
Uninstall IE7
You should have IE6 back again now

Then install the new version you downloaded

I had the same problem. Tried all of the above listed fixes and still no luck. Funny thing is I've never installed any Internet Explorer programs on my laptop. I only use Firefox. The same message still pops up. I have no taskbar, no start button, no desktop files. Can't open antivirus programs. Oh, and my message displays a problem with ordinal 685, not 166. Any ideas?

Dunedin

Hello Micks_

That certainly sounds like a malware problem to me

Try to start Explorer
Press CTRL + ALT + DEL
If Task Manager opens
File/New Task (Run) and type in
explorer.exe
OK

If that gets your Start menu etc back follow the instructions I gave about posting in the Virus Help Forum.

Thanks Dunedin! I'll post if it works.
