Windows 10: .NET Framework 3.5 Not installing

.NET Framework 3.5 won't install! It just gives me this error message:

Windows couldn't find the required files to complete the requested changes. Make sure you're connect to Internet, and try again.
Error code: 0x800F081F


Any suggestions? Please help me soon! *Sad

unexpected error occurred while troubleshooting

Upgraded to 1607 but unable to get .Net framework 3.5 windows update as it is required , when tried to install .Net 3.5 framework.

Why windows update is required for installing .Net framework 3.5?

 

.NET framework v. 2.0 does not seem to load

Did you install the .NET Framework 3.5? It should contain all the run times for previous versions of the .NET framework such as version 2.0.

I posted this earlier after 14342 came out. See if this gets you there. If you have questions or need help, please post back. TC

So do I do
DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:e:\sources\sxs
in an admin cmd prompt?

Drive 'E' is where Windows 10 installed.

 

Yes, at admin cmd. The "e" above refers to the drive letter assigned by windows when you mount the ISO for build 14342, not where windows is installed. Do you have the ISO? Do you still have the $BT~ folder from the build update in the root drive C? Please let me know these two things. It's fairly simple, but I need to know a few things first.

 

Can you tell me where the $BT folder is?

 

And what do you mean by "mounting" the ISO?

And I'm not sure where exactly the ISO is... (that might be a problem)

 

Pdragon, let's back up a little and get some basic info. What version of Windows are you running? Hold the Windows key down and press R. In the box, type WINVER and press enter. Please post a screenshot of that display. I'll wait.....

 

pdragon... You are on the "current" public build of Windows Home. It looks like you have not done any cumulative updates and are running as a local account, not an MS account. The most current build is 10586.318. You have 10586.0. How long have you had this installed and where did you get the installation media?

 

I got the media from the official Windows 10 microsoft website.
Windows 10

And I had this build ever since I installed Windows 10

 

I had that build installed ever since I upgraded from Windows 8.1.
Windows 10

 

So you upgraded from Windows 7 or 8. Are you running as a local account or do you have a Microsoft Account?

The source for your media will download and, at your choosing, upgrade your system automatically. It's the Media Creation Tool. One more question (I think) before I get to a possible fix. Have you done a check for updates since you installed it? You should have gotten at least a cumulative update and a few other things, that would have brought you up to 10586.318. This is important.

 

I have a Microsoft Account, and no, I don't think I have recently checked for updates.
