.net framework 3.5 Error code: 0x800F081F

windows-10 .net

After quite a bit of looking I found the answer to my issue. Here is what fixed it. You must have a copy of the Windows 10 Setup Disk or an iso mounted with the setup files.

From an Admin launch of command prompt run:

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

Note: For the Windows 10 Installer on USB Stick, use:

Dism /online /enable-feature /featurename:NetFx3 /All /Source:F:\x64\sources\sxs

Where F: is the drive letter where the setup disk or virtual disk with the Windows 10 setup files are located. The command prompt will run through a repair and activation of the .net framework feature.
