Error installing Net Framework Feature on server 2016
I am getting an error when trying to install Net Framework 3.5 feature on a virtual server 2016.
I get the error "The request to add or remove features on the specified server failed.
Installation of one or more roles, role services, or features failed.
The referenced assembly could not be found. Error 0x80073701"
I have tried to mount the server 2016 iso and selected the "specify an alternate path" and pointed to the mounted ISO sources\sxs folder and still get the same error. I have also tried to point the alternate path to an extracted copy of the the ISO and still get the error.
Any suggestions at what else I might try would be appreciated.

Thanks for the quick response.
I tried to install via DISM as you suggested but it failed with
"Error: 50
The operations is complete but NetFx3 feature was not enabled."
I have attached the dism log.
dism.log

Can you provide this log? %WINDIR%\logs\CBS\cbs.log
I made a little modification...
I suggested more options... WSUS and downloading the package from Microsoft. Is it possible to try them?

Thanks again for the help.
I tried:
dism /online /enable-feature /featurename:Neff3 /all /Source:c:\ws2016-dist\sou
but got this error
Error: 14081
The referenced assembly could not be found.
Not sure why it wouldn't find the source. as the C:\WS2016-DIST\Sources\sxs
microsoft-windows-netfx3-o
I had prviously tried to download the net framework 3.5 download from MS but it wouldn't install. Just said I had to use the load feature to install.
Thanks

Make sure there are no pending updates and reboot the server if posible. If you use the command I provided without the /source part, it will use Windows Update to download the file.
DISM /Online /Enable-Feature /FeatureName:NetFx3 /All
