when you machine turn,

now again open browse from same above mention method after this copy the downloaded file to

c:\windows\system32

restart you device or simply goto back and open explorer all you desktop will appear as normal without error best of luck with it tested 100 per works

if your have prob watch video or download the file to some other machine and copy using usb stick and paste it above directory

or 2nd method if first failed

That is usually “C:\WINDOWS\SYSTEM32”
The Simplest Option
1. Burn the above file to a CD.
2. Boot into Windows, hit OK when you get the “iertutil.dll” error and then press CTRL-SHIFT-ESCAPE. This should bring up the task manager. You may continue to receive errors while doing this, but just keep clicking OK. Then click File, Run…, and type in CMD and hit Enter.
3. You should now be at a command prompt. Change to your CD drive by typing its drive letter. So to change to drive D: you would simply type “D:” and hit Enter.
4. Copy the iertutil.dll file from the CD to your hard drive by typing
copy iertutil.dll C:\windows\system32
and hit Enter. Obviously change drive letters as appropriate.
