title: Installing a particular file in the GAC?
body: <p>when I wanna to run a click once deployed vb.net win-application on my machine it says:</p>
  
  <p>"Unable to install or run the application. The application requires that assembly CrystalDecisions.CrystalReports.Engine Version 10.2.3600.0 be installed in the Global Assembly Cache(GAC) first."</p>
