See inner exception for details. ---> System.IO.FileLoadException: Filename: \\?\C:\Windows\system32\inetsrv\config\applicationHost.config
Error: Cannot commit configuration changes because the file has changed on disk
The issue can occur because of a timing problem during the setup process. Specifically, another process made a change to the Applicationhost.config file while the Windows SBS setup was trying to edit the same file.
