I am running the .NET 3.5 offline installer on windows 8.1 from Microsoft .NET Framework 3.5 Service pack 1 (Full Package) . Though, when I run this exe, it still prompts me khổng lồ install from windows update. The same thing happens with the pre-service pack installer.

Bạn đang xem: Download

Even if I am connected khổng lồ the internet, the download never completes & freezes on "Downloading required files"

Does anyone have any insight to what could be wrong?


Edit: Daniel B brought khổng lồ my attention that this package is not supported for windows 8.1. I will be taking the route of installing via the windows 8.1 ISO.

Supported Operating System

Windows vps 2003, Windows server 2008, Windows Vista, Windows XP

You need the Windows DVD or ISO. Then use:

DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:d:sourcessxsNote that /Online means the working image of Windows, not an online install

I was unable to lớn DISM for this because the sxs folder diddnt exist on my 8.1 DVD so I did a search and found the update on the DVD, its under supportframework_3.5I ran that & it updated it, works fine.Brian.
