Troubleshooting and Repairing Problems with the Microsoft .NET Framework

The Microsoft .NET Framework helps software developers create applications quickly, efficiently, and with less "code clutter". More info

Because TurboTax for Windows relies heavily on the .NET Framework, it's crucial that the .NET Framework files on your computer are up-to-date and functional.

TurboTax for Windows 2013-2015 require Microsoft .NET Framework 4.0 or 4.5.

TurboTax for Windows 2016 will require .NET Framework 4.5.2

  • Windows 10 Has .NET Framework 4.6 Installed
  • Windows 7 and Vista already have .NET 4.0 installed, with automatic updates.
  • Windows 8 has .NET 4.5 installed, with automatic updates.
  • Windows XP may have .NET Framework 4.0 installed; you can find out by opening Control Panel and double-clicking Add or Remove Programs. If you don't have it, TurboTax will attempt to install it along with the program.

Troubleshooting/Repairing

If you encounter errors or other problems with .NET, the first thing you want to do is download and run Microsoft's .NET Framework Repair Tool.

If that doesn't resolve your issue, run the System File Checker. Then, open Control Panel and choose Programs and Files (or Add or Remove Programs in XP), locate the .NET Framework 4, double-click it and then choose Repair.

Hopefully that should take care of things. If not, visit Microsoft employee and .NET expert Aaron Stebner's WebLog and carefully (we cannot emphasize this enough!) follow his directions to download and run the .NET Framework Cleanup tool. When finished, download and install .NET Framework 4 from Microsoft's site.
