    checking the installation guide, it looks like Sitecore 6.5 supports up to Windows 7 and IIS 7.5. My guess the installer doesn't know how to handle a higher IIS versions so it thinks you are on a lower environment Aug 15, 2018 at 20:52

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
