After uninstalling, downloading from the link you supplied, and trying to reinstall, I now get the error during the installation 😥
Sorry to here that. Our phone support team (1-888-829-8608) can do more advanced trouble shooting on problems like this.
After a pretty lengthy discussion with a very helpful support agent on the phone, it appears that Turbotax has a dependency on a particular version of the Visual C++ runtime that is out of date, and won't install if you have a newer version that is actually supported :(
Not a great experience... I'll have to try installed on a older PC rather than one that is running a fully supported OS.
