If your IE browser has a problem, I want to reload the same IE as the original version. If you are directly installed, the system will prompt you that you have installed the browser, what should I do? Don't worry, the installer automatically left the IE that has been installed in the system registry before installing the IE browser, so you will have the above errors when you reinstall it again. Ok, look at the solution!
Enter the registry! (Operation -> regedit, don't tell me?) Find "HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / ActiveSetup / Installed Components / {89820200-ECBD-11CF-8B85-00AA005B4383}" → Change the dwod value "Isintalled" from 1 to 0 . Find "HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / ActiveSetup / Installed Components / {44BBA840-CC51-11CF-AAFA-00AA00B6015C}" → change the DWOD value "IsIndalled" from 1 to 0. It can be reloaded in the future.
