title: Visual Studio 2010 not starting - Missing ATL100.DLL
body: <p>I tried to start Visual Studio and it said: <code>"This application has failed to start because ATL100.DLL was not found. Re-installing the application may fix this problem"</code>.
  <br />I don't want to reinstall it (time consuming).<br />
  I also just uninstalled all the C++ stuff (I don't do any C++ work, so I got rid of it).<br /></p>
  
  <p>So does anyone know?</p>
