GitHub Desktop Installation

I am attempting to install GitHub Desktop on my Windows 10 x64 computer. When I attempt to run the .exe installer, I am met with an error message saying that installation has failed. Running the .exe file as an administrator produces the same error. I then tried installing SourceTree as an alternative to GitHub Desktop but was met with the same error.

Not sure where to go from here in terms of troubleshooting. The contents of the Setup Log are included in THIS LINK.
