There are also many online People encounter this problem and post the error log, and then the response is generally: the installation package has a problem, the next iso or online installation and other answers, and the probability of this method to solve the problem seems to be gray .

In fact, there is a possible problem: there is a problem with the permissions of

HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Internet Explorer\\Main\\FeatureControl\\FEATURE_RESTRICT_ABOUT_PROTOCOL_IE7 in the registry. If some optimization software is installed, the "full read" permission may be given, and only the "read” permission is given. As long as you manually open the "Complete Read" permission, there should be a possibility of resolution.

Of course, this is just one of a variety of error situations. The specific problem depends on the error log at the time.
