Question

Friday, April 13, 2018 5:25 PM

Windows 10 1709 installed. Attempting to install .Net Framework 3.5 and receiving error 0x080240438.
There is nothing else viable to find with this error code on other forums.

Any help appreciated, thank you.

That does not look like a valid error code.

Are you sure you copied the right string?

Hi Lord Bobbymort.

How are you trying to install .NET Framework 3.5 on Windows 10? Are you using the Windows 10 Features Activation functionality?

You could also try using the Deployment Image Servicing and Management (DISM) tool: read here to know how to do that.

Bye.

Best way is to install by direct internet.

Provide Internet to Win 10 PC then install from Intenet.

yes, that is the string. 
copied from CMD after receiving the same results and error using DISM command in CMD because I can't copy from the Windows Features installer window: 0x80240438 (i accidentally posted a zero before the code in the initial post)

yes. installing via the Windows Features installer directly, or having the Windows Features installer open automatically while I'm trying to install the program that requires it.
I receive the same error after using the DISM command: "DISM /Online /Enable-Feature /FeatureName:NetFx3 /All"

Hi Lord Bobbymort,

To fix this problem, make sure that the full path of the source is correct (x:\sources\sxs) and that you have at least Read access to the location. To do this, try to access the source directly from the affected computer. Verify that the installation source contains a valid and complete set of files.

Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:R:\sources\SxS**\microsoft-windows-netfx3-ondemand-package.cab**/LimitAccess

Hope it will be helpful to you
