After following the installation instructions from this video https://www.youtube.com/watch?v=K7T_JjvEamg
until timecode 9:30 the application doesn´t appear in the webbrowser. Instead i got a HTTP-Error 500.19. I searched for the error and found following information:
This problem occurs when the file „ApplicationHost.config“ or „Web.config“ include wrong or none known XML-Element IIS can´t identify thee XML-Element or non installed Modules. Example: IIS-Modul URL Rewrite.
Solution:
Follow the solution instructions below...
Delete the wrong formatted XML-Elements in the file „ApplicationHost.config“ or „Web.config“.
Check on not identified XML-Elements, and install the required IIS-Module.

I am not sure what to do exactly or whats wrong at this point, because i followed the instructions whithout problems. Only the circumstance, that the webplattform installer does not any longer work. so i installed the needed products manually.
What can i do?

    Download the raw web.config file from GitHub and replace your current one with this newly downloaded one and retest. It seems you have a web.config that your server doesn’t like.

    Cheers.

      Hi Kevin thx for your help, but nothing changed. Think it is another fault in my installation. The web.config file seems to be 9 years old in git

        Yes, it hasn't changed in 9 years as it doesn't need to change. Still works fine with old/latest IIS builds. Maybe just try removing that file completely.

        Cheers.

            My experience with this error has been that the URL Re-Write module [https://www.iis.net/downloads/microsoft/url-rewrite] is missing and needs to be installed on IIS as it is defined and referenced in the default web.config file.

            By removing the web.config file you remove the reference to it which is why the error is no longer present after removal.

            Not sure what all else is in the web.config that OST may rely on (if anything) but my solution on IIS was the URL Re-Write.
