If it works, you can set your computer to clean boot

I tried the suggested fix, but it didn't work.  I was able to do the clean boot, unfortunately, the iertutil.dll errors were still present.  While in safe mode, I pulled up the command prompt and entered "scf /scannow"  after a lengthy wait, the program found several errors and repaired them.  After a fresh reboot, all the iertutil.dll errors were gone.  I had to reinstall a few programs, but other than that minor inconvenience, everything is back to normal.
