Windows – Error installing .NET Framework 3.5 on Windows 10

.net frameworkinstallationwindows 10

Since I upgraded to Windows 10 I'm no longer a "real" administrator on my personal computer and I can't download anything from Windows Update.

When I try to install .NET 3.5 I get

Error 0x800F081F

I already tried to change the source directly in the command panel (as admin) but it gave me a error message that the source was not found with the same error code.

I prefer the method 3: Use Windows installation media.

You can use the Windows installation media as the file source when you enable the .NET Framework 3.5 feature. To do this, follow these steps:

  • Insert the Windows installation media.
  • At an elevated command prompt, run the following command:

Dism /online /enable-feature /featurename:NetFx3 /All /Source:<drive>:\sources\sxs /LimitAccess

  • Note In this command, is a placeholder for the drive letter for the DVD drive or for the Windows installation media. For example, you run the following command:

Dism /online /enable-feature /featurename:NetFx3 /All /Source:D:\sources\sxs /LimitAccess
