Installing .NET Framework 3.5 can only be done through Windows Features on Windows 7. What is not working?  (a) The Feature?  or (b) something that depends on the Feature?

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.

Go here:

and download netfx_setupverifier_new .

I did and ran it. Everything from V2 forward to V4 runs successfully and verifies. V1.1 does not, but that probably does not matter to me.

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
