title: Cannot reinstall Microsoft .NET Framework 4.5 or 4.51
body: <p>I am using Windows 8 and I uninstalled Microsoft Frameworks 4.5 and 4.51 because a blog suggested reinstalling these if I had issues debugging in Visual Studio.  I uninstalled them in the control panel in the programs and features section.  I downloaded the web install frameworks for both from Microsoft's site, but when I run them, I get a message that says "The .net framework 4.5 and this update are already installed on your computer".</p>
  
  <p>I tried a .net cleanup utility, but it says "ERROR Cannot remove product '.NET Framework 4.5' because it is not allowed on the current OS"</p>
  
  <p>I uninstalled the following from the control panel:</p>
  
  <ul>
  <li>Microsoft .NET Framework 4.5 Multi-Targeting Pack </li>
  <li>Microsoft .NET Framework 4.5 SDK </li>
  <li>Microsoft .NET Framework 4.51 Multi-Targeting Pack</li>
  <li>Microsoft .NET Framework 4.51 Multi-Targeting Pack (ENU) </li>
  <li>Microsoft .NET Framework 4.51 SDK</li>
  </ul>
  
  <p>I am not sure how to re-install the .net frameworks or if there is another place I need to go to remove .net framework 4.5 completely before reinstalling it.</p>
  
  <p>Any suggestions would be appreciated.
  Thanks</p>
