Windows 10 Can't Install 3.5 Net Framework

[dl0802]

Tried installing in order to play Smite. Windows installer fails when I try to turn on the feature in the Windows Features application, says it cannot find the file specified. Feel free to ask for more info, also I have tried many different solutions such as using an installation media, command line, trying to download off of Microsoft's website. Please post anything that could help, and thank you.

it comes with 3.5 and 4.7 .netframework pre installed so you shouldnt need to install it.
1) go to add remove programs in the control panel. then add remove windows features and it should be highlighted as in use there.

if its not.

2) enable it and let windows install it.
3) if it fails to install then try running sfc /scannow from the cmd prompt then goto 1

I tried that earlier today while googling some solutions, got the same error then. Tried it again just in case, but still the same error occurs.

Please follow below steps to install dot net 3.5 on windows 10

1. Insert windows 10 DVD in drive/ Mount Windows !0 ISO and note the drive name (mount point)
2. open command prompt using administrator credentials.
3. type following command replacing "x" with the drive name from step 1 and press enter

Tried it, I'm getting error 87, "The enable-featurename option is unknown." Am I supposed to the replace all the "x" with my drive name or only the one after source?

as for error 87 The DISM log file can be found at C:\Windows\Logs\DISM\dism.log
reading it might help you find the fail point.

this might be easier

Use /All to enable all parent features of the specified feature. For more information on DISM arguments, see Enable or Disable Windows Features Using DISM.

On Windows 8 PCs, after installation .NET Framework 3.5 is displayed as enabled in Turn Windows features on or off in Control Panel. For Windows Server 2012 systems, feature installation state can be viewed in Server Manager.

I'm really not sure what I should be looking for in the DISM log, if you want I can paste it on to here though. I tried the "DISM /Online /Enable-Feature /FeatureName:NetFx3 /All" command and recieved an error 2, "The system cannot find the file specified."

 

[HEXiT]

DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:drive:\sources\sxs
drive: = source of your dvd or iso.

Well that's what I typed when I followed haroon's instructions, didn't work then though. Tried it again now and still not working, instead this time I'm getting an Error 2 once again (before I got an error 87, I probably typed something wrong), that the system cannot find the file specified.
