Can't enable or install .NET Framework 3.5 in Windows 8.1 PRO 64-bit

Anonymous

I continually receive the message in a dialogue that

"Windows couldn't complete the requested changes.

The system cannot find the file specified.

Error code: 0x80070002"

I have not been able to find my way around it. Running on a 4770K system with fresh install, only user, and with Admin privileges, and usually running Command and many other programs as Administrator.

Can't turn 3.5 on through Control Panel "Turn Windows features on or off", although .NET Framework 4.5 Advanced Services IS enabled.

No success either, using installers provided with programs that require that version of .NET. As they do require it, I am hoping to get this resolved.

No success with DISM method of scanhealth & restorehealth, although these run OK.

No success with DISM method to install from distribuion CD, mounted ISO, or folder Sources\sxs folder copied to hard drive (including using /LimitAccess switch).

I haven't been able to figure out from looking at the DISM and CBS logs what might be missing.

No success changing server or path in Administrative Templates, etc. regarding Windows Update, for installing components.

No success from .NET full download or stub from Microsoft website.

Microsoft's Windows Update fix-it tool doesn't come up with a solution, either, or point to the culprit with any useful detail.

I've tried to be reasonably methodical in working this out, but I still don't seem to be getting anywhere.

ANY SUGGESTIONS, PLEASE?

Hi everyone,

I solved the problem .Just copy the single file from sxs folder of windows 10 dvd or iso to your local drive.

Extract this file using winrar.

Now run DISM command wih administrator privilege with extracted folder as a source path

Ex.

dism / online /Enable-Feature /featurename:NetFx3 /All /Source:D:Sources\sxs

That worked for me ! Thanks! I also uninstall all the updates too! Luckly I came across with this problem right after a fresh install of 8.1 PRO 64 bits. Have you tried to refresh your PC?

I had to disable my firewall. I'm not sure why it was blocking, but they must be accessing something other than freaking http. Damn microsoft.

Anyone on domain with WSUS, this is what fixed it for me:

Windows Server Update Services. An error can also occur if your administrator has configured your computer to use Windows Server Update Services (WSUS) instead of Windows Update for servicing. Ask your administrator to enable the policy to use Windows Update instead of WSUS, or you can try the following:
1. On your keyboard, press the Window key , and type gpedit.msc to start the Local Group Policy Editor.
2. Navigate to the Computer Configuration->Administrative Templates->System Folder and find the Specify settings for option component installation setting file.
3. Open the file and select Enabled. In the Options box, check the Contact Windows Update directly to download repair content instead of Windows Server Update Services (WSUS) option. Click OK to close the file.
4. Reboot your computer for the setting to take effect, if prompted to do so.

I was able to resolve the issue by simply taking another installation package, installing it from a scratch on a new VM and providing its sxs folder. Worked like a charm!
