"You must turn Windows Feature on or off" is blank RRS feed

  • Question

  • I'm trying to install Microsoft .net framework 3.5 (which apparently isn't on the computer, Win7) and then it tells me to turn the features on or off, but when I go there it loads for a little while, and then is completely blank, and I would appreciate if anyone has a solution to this.

  • .NET 3.5.1 (includes 2.0, 3.0, 3.5 and patches through 3.5 SP1) comes as part of the Windows 7 OS. Therefore you cannot install 3.5 as a user.

    Lets find out exactly what .NET versions are on your system.

    Please use this tool to identify the .NET versions currently installed on your system:

    Run the tool with the highest available .NET version selected, then post the first 25 lines AND the LAST 10 lines of the tool log here.

    If we find that the embedded frameworks are corrupt, you will need to follow this procedure:

  • The verifier indicates that your Windows 7 is missing .NET 2.0, 3.0 and 3.5. That means the OS has been corrupted.

    As I explained earlier, you cannot use a normal user install process to correct the situation.

    Your only option is the procedure described here:

    http://blogs.msdn.com/b/astebner/archive/2007/03/26/how-to-repair-the-net-framework-2-0-and-3-0-on-windows-vista.aspx

    If that does not correct the .NET 3.5.1 issues, you will need to repair/reinstall your OS.

  • I have tried to do the "sfc /scannow" before, but all it gives is "Beginning system scan. This process will take some time." And a few seconds later it says "Windows Resource Protection could not perform the requested operation." I have looked around on several places, but have not found out how to fix this.

    Does this mean I have to reinstall my OS, or is there another fix?

    EDIT: Once, when I somehow only started the very core files or whatever it is called, where you could choose between Command Prompt and I think 4 other options, the "sfc /scannow" worked, but it asked me to reboot the system and run it again. I did not remember how I got there, so I started in safe mode, but it gave me the "Windows Resource Protection could not perform etc." error message again. How do I get to that part again?

  • I'm sorry to tell you this, but inability to runsfc /scannow is further indication that your Windows 7 is corrupt.

    I suggest you first try any available Win 7 repair techniques before resorting to a complete reinstall. You can get help with your Win 7 issues here:
