I have windows server 2012 and I have installed the IIS 8.5 but I could not see the URL rewrite module. How can I enable or install?
Download it from here
http://www.iis.net/downloads/microsoft/url-rewrite
or if you already have Web Platform Installer on your machine you can install if from there.
First, install the URL Rewrite from a download or from the Web Platform Installer. Second, restart IIS. And, finally, close IIS and open again. The last step worked for me.
Worth mentioning: you should download the x64 version!
From the main download page (https://www.iis.net/downloads/microsoft/url-rewrite) click "additional downloads" (under the main download button) and download the x64 version (because for some reason - the default download version is x86)
