When installing QuickBooks or Microsoft .NET Framework , you receive either of these errors:

  • Error 1935: This setup requires .NET Framework.

  • Error 1935: An error occurred during the installation of assembly

The following can cause the error to occur:

  • Microsoft .NET Framework system files are in use by another installation.
  • Anti-virus/anti-spy ware applications are preventing installation.
  • .NET Framework is not installed, damaged, or a program is preventing the installation.
Solution:
  1. Reboot your computer and start the installation again.
  2. If you have anti-virus or anti-spy ware software, stop it or temporarily disable it and start the installation again.
    • If installation is successful, restart your anti-virus software.
    • If the error occurs again, proceed with the next step.
  3. See Install QuickBooks in Selective Startup for detailed instructions.
  4. If you continue to receive the 1935 error, see repair or reinstall Microsoft .NET Framework and start the installation again.

Note: If the error persists after following the solutions above, Intuit recommends you consult a qualified IT professional or Microsoft as there may be damage to your operating system.
