can't get .NET 3.5 to install on Windows 8.1

[MastaChaOS]

I have an app that needs .NET 2.0 which is included in .NET 3.5.

 

I tried using the "add or remove features" function in Windows to add 3.5 but it failed.

 

After some searching I found the following command which is supposed to install it off the Windows DVD: Dism /online /enable-feature /featurename:NetFx3 /All /Source:D:\sources\sxs /LimitAccess

 

when I run the command I get this error:

Can anyone help me get this installed?  I have an app that requires it that I need to run and it's getting pretty frustrating having nothing work.

 

Thanks!

We had the same problems at work with Server 2012 R2.

It's the most annoying thing that affected me recently. I did a bit of searching online and found this, which worked for me:

 

Uninstall  KB2966826 and KB2966828, then try installing 3.5 from programs and features.

Had this issue on a few machines at work, removing them updates (some machines only had one of them) fixed the problem and allowed me to install .Net Framework 3.5 using the DISM command.

 

I also found that the reason the Add & Remove Features option doesn't work for me is because we are on a domain, take the PC OFF the domain and install, then it works fine. From what I can see it tries to get the install packages from the WSUS server, which of course fails.

Yes, repeatedly.  

I'm attempting to remove the updates now and will post back with my results.
