we haven't seen this in Support till now, but the solution from this blog is worth a try:

  • Shut down and disable services that required .NET 4.
  • Uninstall all .NET 4 components.
  • Open command prompt and change to C:\Windows\Microsoft.NET\Framework\v2.0.50727 . Run Caspol.exe -all -reset to create security.config and security.config.cch files in Config folder.
  • Change to C:\Windows\Microsoft.NET\Framework64\v2.0.50727 and do the same thing for the 64-bit framework.
  • Install .NET 4 from downloaded setup file.
  • rerun SQL Server setup
  • Enabled applications services that require .NET 4
  • restart server

Best regards
