SharePoint 2013

Setup is unable to proceed due to the following error(s): This product requires Microsoft .Net Framework 4.5

I again bring to you another error that may occur during the deployment of SharePoint 2013. I was configuring a farm recently with SharePoint 2013 SP1 on a farm of Server 2012 R2 servers that had been updated to the latest available patches via the onsite Windows Update server.

Server 2012 R2 and SharePoint 2013: The tool was unable to install Application Server Role, Web Server (IIS) Role.

Seriously...WTF. I spent two days trying to figure out this issue and finally I went digging into %WINDIR% to find my answer.

I was trying to run the Prerequisite Installer for SharePoint 2013 on Server 2012 R2 but I kept getting the error in the title line
