Is it possible to enter the TTax system without downloading? Can I enter directly online?
IF you computer truly needs to have the Microsoft.NET Framework 4.5.2 installed it is because your computer DOES NOT have all of the MS updates. Before trying to install TTax, you should first make sure your computer has all required updates installed.
Note that if the Microsoft.NET Framework 4.5.2 update is the only one that is required I believe that it is INCLUDED with the TTax program download and installation (it is included on the CD, but I have never used the download).
