Trouble building Wix 3.11.2

[obermeister42]

I am attempting to build Wix 3.11.2 because my organization needs a code change that was not included in this release, but we are unable to migrate to a later release at this time. So, this is my first time attempting to build Wix.

I started with the "wix3112rtm" tag in the wix3 repo. I am following the steps outlined here to do a release build.

I am using the Visual studio 2019 developer command prompt. I have the following studio versions installed: 2010, 2012, 2013, 2015, 2017, and 2019.

Here is my build command: msbuild /p:Configuration=Release /p:OFFICIAL_WIX_BUILD=C:\wix.snk

Here is the error I'm getting:

LastBuild.log

It appears to pertain to SHFB not being able to find my .NET framwork 4.0. I did some hunting around, and in my \wix3\packages\EWSoftware.SHFB.2014.11.22.0\tools folder there was a file - Frameworks.xml - that had an incorrect path to the framework in question. I've updated this, but it didn't seem to have any effect on the success of my build. I did an search of all the files under wix3 and didn't see any other paths to this framework that are incorrect.

Here is my 'fix" for frameworks.xml:
<Framework Platform=".NETFramework" Version="4.0.30319" Title=".NET Framework 4.0" Redirect=".NET Framework 4 Platform Update 1 (KB2478063)"> <AssemblyLocations> <Location IsCore="true" Path="C:\Windows\Microsoft.NET\Framework\v4.0.30319">

I'm out of ideas at this point. Any idea what I could be doing wrong? I realize this is an older release, but I assume it should be possible to rebuild an older version, assuming I'm doing it in a consistent fashion. That, of course, is the real trick.
