When IIS7.5 opens the Web page, it prompts:
HTTP Error 500.0-internal Server error
Failed to invoke LoadLibraryEx, on ISAPI filter "C:\Windows\Microsoft.NET\Framework\v4.0.30319\\aspnet_filter.dll"

Although opening a PHP Web page prompts. NET Framework error is a bit confusing, but the hint of error is obvious, this path is problematic.

The above path "C:\Windows\Microsoft.NET\Framework\v4.0.30319\Aspnet_filter.dll", apparently the last DLL file name is preceded by a slash, causing the file to be found.

Open IIS Manager, open the properties of the Web site, open the ISAPI filter, double-click asp.net_4.0.30319.0 for editing, and remove the extra slashes from the path.
