  1. Tried that several times but unfortunately the post installation kept failing. Since I saw in the errorlog that it was iis related I tried opening the default web site in iis and also got the dreaded 503 page not found.
    Now in my case the strange but neat part. I just deleted the default web site in iis and all of a sudden the post installation started to work without error message (even with dotnet 4.7 installed)
