Windows 8 and 8.1 do not allow you to install Dot Net 3.5 using an internet connection… which is its default. The solution is to extract the SXS folder from your install media and then run a command line install with the following:
Fear not, .NET 3.5 and .NET 4.5 (which is built into Windows 8.1) function nicely together.

can't i download it the file then run it online apart all other solutions
One word, no. Sorry, it will not install that way.
yes,it works.. thanks
How can I fix this error if I don't have the DVD??? I bought the machine pre-installed with Win 8.1
Using a different computer, I would copy the SXS folder (or the whole DVD) to a thumb drive and then point the script to your thumb drive.
Your instructions do not work. I have tried 4 different
Windows 8 DVD, including the one from Dell, and they all say the file is missing.
Try checking your INSTALLED UPDATES to see if there are any .NET 3.5 updates installed. Yes, I know that should be impossible but I recently ran into this. see: http://www.urtech.ca/2014/09/solved-cannot-install-3-5-on-windows-8-1error-0x800f0906-and-0x800f081f/
It didn't work, I got error: 0x800f081f, File not found, (the source is correct Checked) then it ask me to execute the following comands:
dism.exe /online /cleanup-image /scanhealth
dism.exe /online /cleanup-image /restorehealth
Done it and still got error
You may have the issue I ran into a few days ago which was easy to fix: http://www.urtech.ca/2014/09/solved-cannot-install-3-5-on-windows-8-1error-0x800f0906-and-0x800f081f/
