Working with support from Turbo Tax I was able to resolve the Visual C++ problem.
After numerous failures here is what worked for me:
STEP 1 - go to control panel, programs an uninstall all the visual C++ programs. I had 4. Note that it looks like they are uninstalled but one is not completely uninstalled.
STEP 2 - download on of Microsofts Troubleshooters. Here is the link:
Link to Microsoft
click UNINSTALL. I had to do it twice.
STEP 3 - access Microsoft site to install the latest visual C++. here is the link:
https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170
page down, install 86 first then 64.
After that TT installed OK
