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

Updating my request to see if anyone can explain a portion of my DISM log.  No success with everything already attempted in the following thread, but here it is for review.

http://answers.microsoft.com/en-us/windows/forum/windows8\_1-system/cant-enable-or-install-net-framework-35-in-windows/2f221b25-8d17-421f-8c37-1fed61649b4f

I get 99.8% of the way through for any method to enable, including after repairs of any corrupt files, restorehealth, download of \SXS directory files, etc.  Have used options for WSUS, WU group policy, DVD from .iso, made sure I have all permissions, running as Administrator.  Of course, Control Panel enable and installs from apps needing 3.5 fail as well.  BTW, fresh install was from a Windows 8.1 Pro DVD, NOT as an update or from a Win 8 PRO disc.

Always fails with 0x80070002, even when Windows Update downloads the files.

Running Command Prompt as Administrator, with \SXS files moved to D:\DotNet

dism.exe /online /enable-feature /featurename:NetFX3 /all /limitaccess /Source:D:\DotNet

My DISM log keeps failing here:

So, what does it mean Encountered an unknown option "featurename"?  The option seems to be what is required on the DISM command line, and DISM help indicates that it is valid syntax.

Hi,

That would at least answer part of the question without losing your installed stuff...

It seems as though you've already all of the fixes that I'm aware of, but them that doesn't mean there's not more that I'm not aware of either...

I don't remember if you have tried the sfc /scannow from a .CMD (Admin)

Still stuck for an answer.

I'd rather not have to try a re-install of Win 8.1, as there doesn't seem any way to keep all the programs I've loaded and configured since.  It's also installed on an SSD, though I could try cloning to a hard disk and testing out on the cloned disk.

Hi,

Taking Ownership of the C;\ drive covers about everything... Did you also check subfolders and files ?

A Local Account seems to work better than the Microsoft...

There always will be a few system files that you are Denied Access to change Owner...

There are also some deeper down folders that for some reason don't change, even though there was no error shown... One example might be C:\Windows\System32...

This can usually be corrected by simply doing the Take Ownership process on the troublesome folder...

Kind of a pain, but I've never needed access to virtually every system file\folder on the machine anyway.

I don't know enough about your log to make much sense of it...

I do know that others have had this issue, and were unable to activate .Net 3.5 until after reinstalling Win 8\8.1...

I don't actually know if the problem is with Windows, or a 3rd party program that needs .Net 3.5...

Some of the threads I have been involved in suggest that sometimes a 3rd party program that is dependent on .Net 3.5, that tries to use or install it prior to it being activated, somehow screws up the process..

BTW... I can't find the info at the moment, but it seems to me that I read somewhere about changing the OnLine part of the command to OffLine...
