How to Install the .NET Framework 3.5 on Windows 8.1 RTM

[AR_Alex]

So I came across a problem in which I tried to install a program that required .Net framework 2.0 for the program to be installed and I got this message from windows update to download and install 3.5 so I did but then I got an error (0x800F0906) to be exact. I figured this out to get 3.5 installed so I can finally install my program with windows 8.1.

Step 1: Insert the windows 8.1 RTM installation media (USB or DVD)

Step 2: Open up Command Prompt (admin mode)

Step 3: Run this command - Dism /online /enable-feature /featurename:NetFx3 /All /Source:<drive>:\sources\sxs /LimitAccess
(Replace the <drive> with the letter of your installation media)

Step 4: Just wait till the installation finishes and then install your program :)

Step 5: Thats it you are all done :D

I just found this fix this morning while trying to install Windows Live Mail.

If you have the Windows 8.1 .iso, you can mount it with Windows and do this fix.

Full tutorial http://msdn.microsoft.com/en-us/library/hh506443.aspx

DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:d:\sources\sxs

If you want net 3.5 updatable through windows update, try this code:

DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /Source:d:\sources\sxs

If language packs installed, they must be uninstalled then install NF3.5 and then reinstall language pack.

Try NET framework 3.5 standalone installer for 8.1

It's kind of the same thing but the one I found is the manual way of doing it. But if there is some newbies here go with the gui option so you dont break something lol...
