Get your taxes done using TurboTax

#1...make sure you have installed all the W10 updates that may have come out recently first....and reboot a couple times.  (mine stopped installing until I implemented those W10 updates )

#2...Then try again...

#3....if it still won't install......if you want to try this.......  Rt-click on the .exe file and go to Properties, then select the Compatibility tab and set to install in Windows 8 compatibility mode, then Apply and OK at the bottom of the Properties Window.  Then Run as Administrator from the same rt-click menu.

There have been some issues with installing the Desktop Download from some W10 computers...mostly with W10-Pro and higher flavors of W10  (only one W10-Home....so far).  

IF you don't want to try under W8 compatibility (#3)...go here to check for other issues...mostly Anti-Virus problems:
