You can try to download it again from this link. 

Thank you for choosing TurboTax.

Well, I tried that.  Yes, I downloaded it, but it did not fix the problem.  I also cleaned my cache and cookies.  Didn't work.  I am about to do a Restore, which I do not want to do because of the work at reinstalling programs, but I don't know what else to do.  

Try right-clicking on the TurboTax logo and clicking on run as administrator. 

Also, make sure you do not have a pop-up blocker on.
