    I was unable to extend the schema on a Windows 2019. Your tool completed successfully, but the schema wasn’t extended.

    I went to the DC, opened a command prompt and execute extadsch.exe, but nothing occurs. No log file was created too.

    Then, I launch the explorer and double-click on the extadsch.exe, and I got the following error message.

    The program can’t start because mfc120.dll is missing.

    Installing the Microsoft Visual C++ 2013 Redistributable have solved the problem for me.

    Thank you

    In our env, the security standard doesn’t allow named pipes, only TCP.
    However, even with SQL 2017 installed locally, the tool could not connect to the instance.

    In the end, we got it connected by ignoring the instance name and just putting the FQDN,####
    (where #### was the instance port)

    Hi Guys, now that WinPE is a separate download from the Win10 ADK can this be added in to the next release?

    thanks, Jamie
