title: Visual Studio 2010 doesn't start - missing ATL100.dll
body: <p>After installing Visual Studio 2010 Premium and trying to start it, following error message pops up:
  Program can't be started, ATL100.dll is missing. Reinstall program to solve the problem.</p>
  
  <p>I searched for the ATL100.dll and found it in:</p>
  
  <ul>
  <li>"C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\redist\ia64\Microsoft.VC100.ATL"</li>
  <li>"C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\redist\x64\Microsoft.VC100.ATL"</li>
  <li>"C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\redist\x86\Microsoft.VC100.ATL"</li>
  </ul>
  
  <p>Copying the file to "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE" also won't work.
  Any tips how to fix this problem so i can start VS 2010 ?</p>
