Visual Studio 2015 Deployment via SCCM 2012 R2

I'm looking to create a deployment for Visual Studio 2015 using SCCM 2012 R2. I'm an experienced SCCM Admin, so I'm pretty good on that territory, but I'm running in to a snag with Visual Studio itself.

I'm struggling with creating the XML Admin File. An excerpt from MSDN (https://msdn.microsoft.com/en-us/library/ee225237.aspx) :

To do this, you must first create the AdminDeployment.xml file by using the /CreateAdminFile command-line parameter.

So I run CMD Prompt from the folder that contains my EXE for VS2015 and give the command a try. Here's my command I ran

vs_professional.exe /CreateAdminFile AdminDeployment.xml

And I also tried ...

vs_professional.exe /CreateAdminFile "C:\Users\admin\Downloads\VS2015 Test\AdminDeployment.xml"

After running either of these commands, I see a Visual Studio splash screen for about 30 seconds after which point nothing happens. I've spent a couple hours searching Google and here to see if I can find a hint as to why it might not be working, but have been unable to find any hints to resolving this. Any idea what I'm missing here?

PS: I've tried rebooting my computer and trying again to see if it helps. I've also tried from two PCs (Running Windows 10 Pro and Windows Server 2012 R2 Standard)
