Devart T4 Editor 1.0.9 fails to install for VS 2017 Pro

Question

I've successfully installed this on another machine. Do you see what I need to do on my machine to get this installed? Here's the install log:

you only have Build tools installed, no real SKU. – magicandre1981 May 25 '18 at 13:34 — magicandre1981, May 25 '18 at 13:34

You are installing T4 Editor for Visual Studio 2017, aren't you?
Is Visual Studio Build Tools 2017 installed on your workstation? Refer to https://developercommunity.visualstudio.com/content/problem/32018/vsixinstallerexe-cant-install-extensions-when-visu.html.
Open your VS 2017 Professional > Help > Check for Updates. Apply updates if any. Does this help?

1) Yes, 2) Yes, and that reference may have been the issue, 3) Yes, it did help. I had to both update the VS Build Tools and 2017. One or both fixed the issue. Thank you for taking your time to help here. – Michael Mainer May 26 '18 at 01:10

Thank you @magicandre1981 for the hint.

I have VS 2017 pro installed. I took a look at the error log that results from trying to install T4 editor for VS 2015. The supported product list is more inclusive for T4 editor for VS2015:

5/25/2018 9:29:53 AM -  Supported Products : 
5/25/2018 9:29:53 AM -      Microsoft.VisualStudio.Pro
5/25/2018 9:29:53 AM -          Version : [14.0]
5/25/2018 9:29:53 AM -      Microsoft.VisualStudio.VST_All
5/25/2018 9:29:53 AM -          Version : [14.0]

The installer is looking for only the community SKU for VS 2017. This appears to be the issue here.
