I am trying to install Sitecore 6.5(Sitecore 6.5.0 rev. 110602.exe) from sitecore sdn.I am using windows 10 local server to install sitecore 6.5.However, i am getting an error "IIS is not installed or is a lower version than 5".
The Sitecore Installation Wizard won't support that.
But you can still do it. I recently successfully installed a Sitecore version 6.0 using Sitecore Instance Manager. Download that, and download "Zip Archive of the CMS Root" version of your Sitecore version, and you're good to go.
You'll find it here. Sitecore Instance Manager
