How do I replace ordinal 166 in iertubil.dll?

Posted on 2008-10-09
Last Modified: 2012-05-05
I installed a fresh Windows XP Pro OS on HP laptop running Centrino chip and then ran restore with backup from old hard drive.  Initially I just restored the C drive and the machine booted fine but with apps not functioning properly.  

So I ran restore again and this time restored both the C drive and system state from the backup.  After this completed the machine seems to boot normally until an error message appeared with red circle/white X stating that "The ordinal 166 could not be located in the dynamic link library iertubil.dll"  Closing the error message leaves the machine running but with blank screen.  What has happened and how do I fix it?

You have an outdated DLL - or perhaps a newer DLL than is expected (USUALLY it's outdated).  Reinstall the application that has that message popup when you try to run it. If it's a windows component, I'd verify you're up to date with Windows Update/Microsoft Update and if you still have the problem, try to reapply service pack 3.  Also, you might look at the properties of that dll to find out who created it. (sounds like an IE DLL).

Yes, it does look like an IE DLL judging from the error box.

Only running SP2 but could try to install SP3.  The challenge is how to get on the Internet from blank screen.  How about Safe Mode with networking?

You seem to think an app triggered this problem, but that is not the case.  The error message comes up after boot ... there are no apps running.  In other words, the problem appears to be with the OS.

IE is an integral part of Windows.  It likely is caused by something loading information from the IE DLL.  Check the version you have on another system and trying using that... or download SP3 Network install from Microsoft and run it off CD/flash drive.

OK ... good idea, I'll try that.  I gather you feel SP3 will install enough new code to overcome this problem.  Will report back as soon as completed.  I'll have to try to load from a CD within Safe Mode, as otherwise I cannot operate the ailing machine.

I don't know if you're going to get it to install in safe mode.  If you can't get the system to boot in normal mode, then I'd try to look at the properties of the DLL on that system and compare it to DLLs on other systems, copying a newer version from another system.

Essentially, what happened is that XP SP3 was involuntarily downloaded and installed from Microsoft's website during the course of a routine update.  SP3 corrupted the OS and rendered the machine inoperable.  The "solution" was to reformat the HD and reinstall XP with SP2 and then avoid ALL Microsoft updates.
