Since I'm pretty DOUBTFUL that anyone will actually ACT on this, as it appear to be like that for over 6 years 🙂 Here is a simple "workaround", run the setup.exe, it will fail with the pop up that .NET4.5.2 framework is missing or can't be found, now go to windows temp directory (find location of temp by process pid/file handles)
cp that temp folder, and as a subdirectory you'll find "TurboTax YEAR installer.exe", running this binary applies the updates, essentially skips the (broken) .NET 4.5.2 "Verification".. this is probably not needed on Windows 10, and if .net is broken on win10, that user has much larger issues.
Good luck, hope this helps someone.
Nova.
