I need the Url Rewrite module on my IIS But it does not install and says that I need at least IIS7
Because it took me hours to find the problem, I am posting this solution to my own answer so it will save someone else this work.
In short you have to change the major version of the IIS via the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\InetStp\MajorVersion
to 9 during installation and then back to 10 afterwards.
