Default Windows 8 installation does not include .Net Framework 3.x On a computer that is NOT connected to the Internet you can't install it the 'usual' way: Control Panel -> Programs and Features -> Turn Windows features on or off -> .NET Framework 3.5 as soon as you check the box and hit ok, the system tries to contact Microsoft Web Servers. Here is the way to do it offline: If you are unable to connect your computer to the Internet, you can enable the .NET Framework 3.5 by using the installation media (ISO image or DVD) you installed Windows 8 from. Mount the Windows 8 installation media and type the following command from an [bold]elevated[/bold] command prompt: Code: Dism /online /enable-feature /featurename:NetFx3 /All /Source:x:\sources\sxs /LimitAccess Replace x:\ with the path to your installation media. Hint: In Windows 8 you can mount .iso files by right click -> Mount This may work for other options as well.
please mount the untouched iso in virtual drive and run the command with the virtual drive's letter. you are done
A slightly more offline method. 1) Mount your install.wim w/ dism 2) Run the dism command from the first post, but edit it to point to the mount location, also remove the 'online' switch which defaults to the live OS. 3) Commit the wim and dismount. every new install from that wim, will include netfx3 by default.
4.5 is better for Win8 download.microsoft.com/download/b/a/4/ba4a7e71-2906-4b2d-a0e1-80cf16844f5f/dotnetfx45_full_x86_x64.exe
I just lost my installation file. Did i need to download the file again (about 4 gb +) just to install net.framework ?
Yes, must be applied to each and every image inside your WIM. Documentation says LimitAccess prevents it from going online to get the files. Not sure if that is 'needed', but it probably won't hurt anything.
First because older apps require legacy .net versions to run on W8. Second reason, I'm not sure you are aware, but v4.0 is installed by default, installing it twice won't help.
That's one way of doing it. But may I alternatively suggest using the copy of netfx3 stored on the W8 install DVD in the \Sources\sxs folder.
@jackerz59 1. .Net framework isn't cumulative, so you need 3.5 SP1 which also covers previous versions. 2. The offline installer for .Net Framework 3.5 SP1 doesn't work under Windows 8.
