1. First to exclude the online said installation of the WIN7 is a lite version of the problem, I this is the flagship version, was the normal installation of IIS, and then the program problems I uninstalled, it is not installed
2. Online said to modify what UAC permissions, is also nonsense, because the default is the lowest
3. Exclude the non-administrator rights on the Internet, this knowledge just graduated know whether the administrator landed it.
The Final Solution is:
Uninstall IIS. NET 4.0 with the command first
First step: cd C:\Windows\Microsoft.NET\Framework\v4.0.30319 then Aspnet_regiis.exe-u
Step Two: Install the IIS components with the normal process, and find that there is no problem.
Step three: Install the. NET 4.0 CD C:\Windows\Microsoft.NET\Framework\v4.0.30319 and then Aspnet_regiis.exe-i
OK to solve.
There is also a good way to check the system log at any time is to find the problem. Although there is no log to see this error
Installation Windwos7 IIS has an error, not all of the workarounds for successful changes
