.NET 3.5 Offline installation

I’m testing what I can run on a system away from internet access with windows 11.

Microsoft’s Offline installer is not an Offline installer

Anyone solutions to installing offline?

  • Have a Windows 11 iso mounted, make note of the drive letter it got.
  • Win+R type cmd.exe
  • Copy and paste Dism /online /enable-feature /featurename:NetFX3 /All /Source:D:\sources\sxs /LimitAccess
  • Change “D” with whatever drive letter the iso got.
  • Press “Enter”
  • Watch it work and profit.
