What is the download URI for the ISO of the Microsoft Visual Studio 2013 Update 4 RTM (Offline Installer)?
You can download the current version of the Visual Studio 2013 .ISO at this website. Since the slight redesign of the Visual Studio website, I wasn't able to find a download link, to older updates to Visual Studio 2013.
Due to the nature of the Visual Studio website the download links I had provided to each version of the Visual Studio Update 4 expired in 2014. Instead of trying to find Update 4, I have just updated the links to Visual Studio 2013 Update 5, instead since that is the current version of Visual Studio 2013 anyways.
For the ISO file:
Microsoft Visual Studio Professional 2013 with Update 4 (Offline Installer, also updates existing Visual Studio 2013):

You can also get the installer following the 2 step process:
First download the VS2013.4.exe web installer from Microsoft
Second open a command prompt and run
This will bring up a window that will ask you what location you want to download the offline installer to.
