windows net framework
hello there,
I have windows 7 with visual studio 2010 and net framework v4
I would like to install the net framework 3.5 but it says
"turn windows features on or off"
when I turn it on and off from control panel > programs > turn windows features
it does NOT work and I get that error message all the time..
how can I install it correctly?

how exactly do I install it?
Go to Programs and Features. On the left, click on Windows Features and allow it to load. Then scroll down for .NET Framework 3.5.1 and enable it if is not enabled. I have .NET Framework V4 installed so my .NET 3.5 is checked but greyed out. I think V4 replaces it all.
Also, I have subcomponents that were not enabled (out of the box) and I have not enable them (no apparent need). See below:

I did a bit of reading because of this, and it appears that .NET Framework 3.5.1 as supplied by Windows 7 inlcudes everything back and including V2. I am not certain about V1.1 because it appears separately in the the list of installed programs, but not in the list of installed updates
V4 is additional and was a Windows Update at one point that I allowed to be installed.
Starting from here with Windows 7 is appears that .NET 4 and .NET 3.5.1 should accomodate everything out there. It does for me (as a user). .... Thinkpads_User

You probably have to upgrade the apps to V4 then, because there isn't much else you can do with Windows 7. One article suggested enabling the Foundation components to provide compatiblity. You might try that, but I cannot vouch for it in any way.
Here is a page that describes how to test what is installed by checking registry keys. Do take care, of course, using the Registry.

Please try the tool above. I tried it on my two Windows 7 Pro machines and everything from V2 forward verifies perfectly. I do not even have V1.1 on one machine.
So does it verify for you? And then, assuming so, if you have a problem with an application, it would be an application problem rather than a Windows problem.

XK8ER - Any followup on this? You should at least know whether all your .NET Frameworks are installed. ... Thinkpads_User
