Troubleshoot problems with Windows Installer and the Microsoft .NET Framework

by TurboTax•1• Updated about 21 hours ago

The Microsoft .NET Framework helps software developers create applications quickly, efficiently, and with less code clutter. TurboTax for Windows relies heavily on the .NET Framework, so it's crucial that your .NET system files are up-to-date and functional.

  • Windows 11 comes with .NET Framework 4.8
  • Windows 10 comes with .NET Framework 4.6
  • Windows 8 comes with .NET 4.5, with automatic updates

If you encounter errors or other problems with .NET, download and run Microsoft's .NET Framework Repair Tool.

If that doesn't resolve your issue, run the System File Checker and then open Control Panel and choose Programs and Files. Open .NET Framework 4 and select Repair.

If the issue persists, download and install Microsoft .NET Framework 4 from Microsoft's site.

If you receive a 4- or 5-digit Windows Installer error, we have specific help articles for your situation.
