I just found a completely ridiculous problem. I have Win10 on my laptop. It comes with .NET 4.5 installed but not 3.5. I want to run a game that uses 3.5 (it won't run without it). When I run either the online or offline .NET 3.5 installer, it says I need .NET 3.5 to install .NET 3.5!

Ridiculous error is ridiculous

This is extremely frustrating. Is there a way I can manually install it?

Things I have tried:

  • Running the .NET 3.5 Online Installer (2Mb)
  • Running the .NET 3.5 Offline Installer (237Mb)
  • Using dism.exe as per Method 3 listed here (it says The referenced assembly is not installed on your system.)
  • Running the .NET Verification Tool.
  • Refreshing my Windows (it fails and says nothing has changed)
  • Troubleshooting the installer (it says Incompatible program, which is wrong because I have .NET 4.5 installed)
  • Installing .NET 2.0 (apparently I need .NET 3.5 for that too)

None of these work! Any ideas?

The only way I've found to fix this is to redownload the Windows 10 Installation Media and install Win10 from scratch.

I ran into this same error recently. In my case "Windows Update" was not enabled, but similar to Windows IME, Windows Update seems to be required to fetch .NET Framework 3.5.

.NET 3.5 should already be included with the installation of Windows 10. You can enable it in Windows Features. Try following the steps in this link

To install .NET 3.5 on Windows 10, you need to use Windows Features, and specify the Windows 10 installation source (i.e., the DVD or USB you used to install Windows 10). I use this command most of the time (from an elevated command prompt):

dism /online /enable-feature /featurename:netfx3 /all /source:d:\sources\sxs

Substitute d:\ for your DVD or USB drive, and you should be good to go.
