I sure need some help. I am currently trying to activate .net 3.5 on a system that requires it for an accounting application, and the problem(s) I am running in to are the following:


- When I try to install the feature through the application itself (e.g., I am prompted by Windows) it begins the download and then fails with error 0x8007002.


- When I try to install the feature using DISM, from a local copy of this .cab file : microsoft-windows-netfx3-ondemand-package I get this error:


c:\DISM /online /enable-feature /featurename:NetFX3 /source:C:\sources\sxs /LimitAccess


Deployment Image Servicing and Management tool

Version: 10.0.17763.1


Image Version: 10.0.17763.253


Enabling feature(s)

[=============================100.0%==========================]


Error: 0x800f081f


The source files could not be found.

Use the "Source" option to specify the location of the files that are required to restore the feature. For more information on specifying a source location, see Configure a Windows Repair Source


The DISM log file can be found at c:\Windows\Logs\DISM\dism.log

I have tried stopping the Update Service, deleting the SoftwareUpdate folder (well, re-naming it), restarting the service, and trying the various methods above to update. I've changed group policy on the local machine...I'm just out of ideas.

Please note I CANNOT FORMAT the computer and start anew.

The last two things I can think to try is one, to allow Windows Update to run (this is a new build, only a few weeks old, from Dell) to see if it picks up any "fixes", and, failing that, to upload an .iso image from my local machine to the problem machine (the machine is remote from me) and point DISM at it.

Please, someone, lend a hand.
