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

    Just to clarify, Microsoft's tool for cleanup failed.

    The other cleanup tool, http://www.downloadcrew.com/article/12721-net\_framework\_cleanup\_tool\_5-8-2012

    did exit with a success code of 3010.  According to the logs, it still does not uninstall .NET 4.0 & 4.5, probably as those are components of the Windows 8.1 O/S.  Even if not enabled in the Control Panel, I guess it doesn't actually get removed.

    However, an attempt, after the re-boot, to install 3.5 continues to fail with the same error.  Persistent little bugger, isn't it?

    I think the last method you haven't give it a try so far is at Microsoft download to search for .net download. give it a try to download and install.

    I have.  first, MS said there was not a downloadable version.  However, there is a .NET 3.5 Service Pack (full & stub) and those both fail.  I think I mentioned it in an earlier post.

    After doing MS .NET Framework repair, I was able to start an installation that at least did a substantial download from Windows Update, but, again, that failed with the same error.

    Hi,

    .Net 4.0 probably isn't related to the problem... I just mentioned that as an example...

    If you are getting some kind of error concerning Ownership, I can think of two things to check...

    Are you using a Microsoft Account ? If so, try switching to a Local Account. It has less restrictions...

    Another thing to try is to Take Ownership of the directory in question... or the entire C:\ drive...

    I do this as a standard practice on all of my installations... Just because I get tired of getting Access Denied messages... I still get a few, but most everything is accessible.

    It's best to do this from THIS PC on the Desktop....

    Open Properties of the drive or directory and select the Security tab, and then Advanced at the bottom, to get to the Ownership area...

    You might just try adding your User name to the Permissions, but you most likely will need to take ownership to do that.
