I can install Xamarin using Visual Studio 2015's "Cross Platform mobile Development" setup option, which gives me Xamarin version 184.108.40.206. This version is operational and I can build and debug Xamarin projects.
Attempting to update this install using Visual Studio 2015's "Tools/Options/Xamarin/Other/Check Now" link finds version 220.127.116.113, which downloads and runs, but ends with the stated problem without performing the install.
I manually downloaded Xamarin.VisualStudio_18.104.22.1688.msi, .695, .680, and even 22.214.171.124. All fail with the same problem and do not perform the update.
I cannot find any log files that might describe why these updates fail.
I have tried uninstalling and reinstalling Xamarin using Visual Studio's setup but this does not change the result.
Any suggestions as to
1. Where I can find a setup or install log file that might have additional information on the setup failure, and
2. What things I could look for on my machine to make these updates work?
I am running Windows 7 x64 with all the latest updates.

Being that the msi is flat out failing, could you please attach diagnostic msi installation logs?
You can get it by running the following command from the cmd prompt:
msiexec /i <path_to_msi> /L*V C:\Logs\xamarin_msi.xml
