.Netframework 3.5.1 on windows 7 RRS feed

  • Question

  • Dear Sir, I am using Windows 7 professional 64 bit on my dell laptop. Last week I accidentally deleted few files from the control panel which included .netframework related files. Now I am not able to use my cd dvd drive. Drive does not recognize any cd other than windows installation cd supplied by dell with original purchase. Even I cannot download any bios or other drivers from dell official website. I have tried to download .netframework 3.5 but iit does not get downloaded. It ends by displaying msg that go to Turn windows feature on or off from control panel. If I do so and check the box in front of .Netframework 3.5.1 then also it does not get visible on add or remove progrram menu on control panel. And even I am not able to download the firefox add on for .netframework 3.5. It shows that primary software is not installed. Please help me to regain my previous settings without altogether reinstalling the whole OS. Thanks.

  • Hi Kaushiik,

    As  far as I know the cd/dvd drivers has nothing to do with .NET framework,  go to control panel and  click Turn windows features on/off insert your windows installation dvd, and click ok. So it will install .NET if necessary.

    Thanks for your post,
