"This application has failed to start because iertutil.dll was not found"

Whenever I try to open any application that is installed on my laptop, a message comes up saying that "this application failed to start because iertutil.dll was not found". It tells me little else other than that.

This started after I tried to fix a different problem on my laptop. Last night I installed some updates, before shutting down my computer. This morning, my computer would freeze completely after I turned it on. It eventually stopped freezing long enough to get to a screen with the message "Configuring updates: Stage 3 0f 3 - 0% complete, etc." I tried to get around this problem by using a solution that I found when searching the problem online. The solution had me select "repair computer" option when the laptop was first turned on. It then had me open up a command prompt and rename a file called pending.xml. Afterwards, I was able to log in just fine, but, then the iertutil.ll problem arose.

Nearly everywhere I have looked, I've found only Windows XP users suffering from this issue, and most of th solutions offered require windows explorer to be working (which is among th many applications on my computer that is adamently refusing to work). If you can help me out, then I canassure you it will be greatly appreciated.

Hi,

·        What are the updates that you tried to install on the system?

 

Let us know the Kb article number of the updates. Follow the steps mentioned in the link given below to check what updates are installed on the system.

InstallWindows updates

http://windows.microsoft.com/en-US/windows-vista/Install-Windows-updates

Troubleshoot problems with installing updates

Iertutil.dll errors are caused by situations that lead to the removal or corruption of the iertutil DLL file.

Apart from that, follow the steps mentioned below.

 

Method 1:

I would suggest you to perform a SFC (System File Checker) scan on the system and check whether the issue is resolved.

a.       Click Start, click All Programs, click Accessories, right-click Command Prompt, and  select Run as Administrator.

b.      Click Continue or supply Administrator credentials if prompted. 

c.       In the Command Prompt window type the following, and press Enter:

d.      sfc /scannow

e.      You should see the following on-screen message:

§ Beginning the system scan. This process will take some time.

§ Beginning verification phase of system scan.

f.        Verification % complete. 

g.       Once the scan has completed, test to see whether the issue that you are experiencing is resolved or not.

For further reference, check the KB article mentioned below.

Method 2:

I would suggest you to do a clean boot and check whether the issue persists in the clean boot mode.
