title: Windows 7 Visual Studio 2005 compatibility
body: <p>I'm now working on RC Windows 7 and installed <a href="http://en.wikipedia.org/wiki/Microsoft_Visual_Studio#Visual_Studio_2008" rel="nofollow noreferrer">Visual&nbsp;Studio&nbsp;2008</a> Professional edition. But I need to work with Java programs, and so I needed to work with <a href="http://en.wikipedia.org/wiki/Microsoft_Visual_Studio#Visual_Studio_2005" rel="nofollow noreferrer">Visual&nbsp;Studio&nbsp;2005</a>. I installed Visual Studio 2005 SP1 (VS80sp1-KB926747), but I have the following problem:</p>
  
  <blockquote>
    <p>"The upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program. Verify that the program to be upgraded exists on your computer and that you have the correct upgrade patch." </p>

  <p>I previously had the same problem when I installed the Visual Studio SDK, February2007.</p>
