Microsoft .NET 3.5 Framework - Where is it?

I have a windows 8 laptop and there is software that I need to install that requires that I already have Microsoft .NET 3.5 Framework. However, how do I determine if I have it on my laptop? I tried the instructions for Start, regedit, etc. and also looked in Control Panel, Program Features, but didn't see anything that was obvious.

Mostly all legitimate programs that require .net 3.5 will recognize if you do not have it and prompt you to "click OK" to install it. Once done, that insatller will fetch it and install it for you. I would just start the installer and see what happens. Good luck.

It's a'll built in to Windows 8 Except for dot net 2.0 - As it shows in TopGun's image.

You cannot install it outside of Windows 8, and it gets installed and set up during a fresh install. You can add or remove parts of it using Windows Features, but if you de-select it then re-select it, it will only mark the main parts of it for install. Also, if you are upgrading Windows XP or 7 and any of your Dot Net's are fouled up, it will transfer that foul up straight over into 8. So before you upgrade, use the Dot Net repair tool and make sure it's all working right.

The Biggest Culprit is Steam, which uses not only Dot net 4 or 4.5, but also Direct X 10. If your Steam is not working in 7, it will not work in 8 either.

This is incorrect. Windows 8 does not install Netframework 3.5 automatically.
In addition to what My2Cents's post above:
  1. 3rd party software that require the net framework will either install it or prompt you to install it
    For example: Nero Burning software, Object Dock from stardock...
  2. You can install it by turning on the Program Software Features.
  3. In some case, you'll get an error installing it (Error code 0x800f0906, 0x800F081F) then you can use DISM command line to install from the installation disk:
    DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:X:\sources\sxs

    Where X is the drive letter of the installation disk

This is incorrect. Windows 8 does not install Netframework 3.5 automatically.


Sorry, but on every fresh install I have done, it did install. The Programs I have that require it, did not install it and they worked. Also, I tried installing the package manually and I got a message that said that it could only be installed or removed via the Features. Maybe some version of Windows 8 you worked with did not have it turned on, but it is still there in the Features section and I'll bet the Installer did not work and you got a similar message. This is Three machines I've seen that message on. But I have never had to install it or add it from the Features because it was already there and selected.

Actually my version of 8 also has 2.0 and 3.0 added to the 3.5 pack: This is exactly how it looked from day one on installing 8. Yours is the same way, so I was wrong about having to add 2.0 manually.

dotnet35.png

And it was installed from day one. I just checked my other system, and it is the same way. Both Windows 8 Pro, the other machine has Media Center.

Maybe what you mean is that it was not installed on your system, you added it later. But it cannot be installed by downloading the installer and trying to install it that way, 3 machines I tried this on refused, that was when I discovered it was already there. I always install Dot Net 2 and 3 on machines just after a fresh installation of Windows 7, that's what I was trying to do when I discovered it was already there.

I've never had to do that, but I'll bookmark the page.

In fact, maybe the first time I used a program that required it, it may have been installed then, but I don't remember it- I've never seen that Popup Window, the next time I do an fresh 8 install, I'll check it and see if it was installed or not.

I wanted to see once and for all, if I was totally mistaken about this, but I am on my Dell Precision 370, which is a fresh install I did about 2 months ago for Testing. I've never tried to install any Dot Net 3.5 and below, this is what it was by default:

DotNet3.png


But I have one Program which requires Dot Net 2, it never asked me about installing any prerequisites, it just went in. Perhaps it installed the needed prerequisite automatically.

Yes, some software will silently install the needed components.

I took the "Gray" (Smaller Black Square) to mean that not all of the selections in that Feature were installed, for it to be totally non installed, it has to be completely blank. Thats what it did when I removed Hyper-V.

For instance, my Dot Net 4 Feature is the same "Neutral" Square, but I KNOW that it is installed. It's the same way on the rest of my machines.

Insert windows installation disc or flash drive, disconnect internet, and run this command on elevated command prompt:
Code:
dism.exe /online /enable-feature /featurename:NetFX3 /Source:x:\sources\sxs
Where "x" is the installation drive letter.

Yah but as I was saying, this should not need to be done, 2 fresh installs and one upgrade put Dot net 3 in there and working. I take the half-black button as "Installed" rather than "Not Installed"

    Recently lost my Windows 8 on my main PC, had to go back to Windows 7.
.NET 3.5 is built upon the .NET 2.0 framework runtime (as is .net 3.0). .NET 4.0, 4.5, and the about to be released 4.5.1 are all based on the 4.0 framework runtime. So when you install .NET 3.5, you also get 3.0 and 2.0. In other words, 3.5 requires 2.0 to work.

The black square means "intermediate" state (not fully cleared and not fully selected), which means that not all of the selections in the category below are selected, but some are. (you'll notice it only applies to sections that have a + sign next to them to expand)

You can install .net 3.5 from the Windows Features dialog, or by using dism from a command line. Either is fine. .net 3.5 is not installed by default with Windows 8. Some apps are smart enough to use dism to install it.

The black square means "intermediate" state (not fully cleared and not fully selected), which means that not all of the selections in the category below are selected, but some are. (you'll notice it only applies to sections that have a + sign next to them to expand)

You can install .net 3.5 from the Windows Features dialog, or by using dism from a command line. Either is fine. .net 3.5 is not installed by default with Windows 8. Some apps are smart enough to use dism to install it.

That may be true, about some program installers using DISM, but two fresh installs and one upgrade were in the "Intermediate" state after installing. Also a brand new Laptop I ordered. And I know that the two programs I use that need it are not that sophisticated, they do not use DISM in the installer, old programs (ie, dot net 3 was new for the version of the program I use).
