Installation Wants me to install IIS even though it it already installed
The installation prereqs want to install IIS even though version 8.5.9600.16384 is already installed. I definitely do not want to be mucking around reinstalling IIS - is there anyway around this? Currently I see the option to proceed and re-install IIS or cancel and exit the installation. This is a development machine, but certainly wouldn't want to run into this issue on a production machine either. Thanks.
Which package/version are you installing? I assume you are installing CES.
My guess is that some IIS feature might be missing. The install kit detects whether IIS is installed by checking those registry keys:
HKLM\SOFTWARE\Microsoft\InetStp\Components\CoreWebEngine HKLM\SOFTWARE\Microsoft\InetStp\Components\ASPNET HKLM\SOFTWARE\Microsoft\InetStp\Components\BasicAuthentication HKLM\SOFTWARE\Microsoft\InetStp\Components\WindowsAuthentication HKLM\SOFTWARE\Microsoft\InetStp\Components\WMICompatibility HKLM\SOFTWARE\Microsoft\InetStp\Components\Metabase HKLM\SOFTWARE\Microsoft\InetStp\Components\ADSICompatibility HKLM\SOFTWARE\Microsoft\InetStp\Components\LegacyScripts
