title: cannot install .NET Framework 3.5
body: <p>I already have installed Microsoft Visual Studio 2008 SP1 and VS 2010 SP1. I'm using Windows 7.</p>
  
  <p>Then, I noticed in my Installed Programs in Control Panel that only the following were the installed .NET Frameworks:</p>
  
  <ul>
  <li>Microsoft .NET Compact Framework 2.0 SP2</li>
  <li>Microsoft .NET Compact Framework 3.5</li>
  <li>Microsoft .NET Framework 4 Client Profile</li>
  <li>Microsoft .NET Framework 4 Extended.</li>
  </ul>
  
  <p>For some reasons, when I was installing PowerCommands for Visual Studio 2008, it says that I need to install .NET Framework 3.5.</p>
  
  <p>When I tried to use dotnetfx35.exe, it just unpacks the installer, but doesn't proceed with the setup process.</p>
  
  <p>Is this just because I'm using Windows 7? Or is there a proper way of setting up .NET Framework 3.5?</p>
  
  <p>Thanks!</p>
