Step 3 - Clean Out The Registry
One of the big causes of the iertutil.dll error is the way in which there are a series of mis-matches inside the registry of your system. The registry is a central database which stores all the files, settings and options that Windows uses to run. Although this part of your computer is one of the most important, it’s also a big cause of errors because of the way that Windows will often corrupt it.
Not many people realize this, but the registry will continually cause a large number of DLL errors because of the way in which your computer uses a large list of DLL files to help it run. Each time you use your PC, 100’s of DLL files are being loaded with help from the registry database. If this database gets corrupted / damaged, it leads to your system showing errors like the one you’re seeing, making it highly recommended that you repair any problems inside the registry.
