Well,
the CR i'm using to develop is the 13.0.1.220.
.NET framework 3.5.
I'm using Visual Studio 2010 to deploy it in a private server in the network, using ClickOnce, so i don't know how to answer your question about where did i download the Clickonce file, cause that is native on Windows Forms Application using VS2010.
The OS i'm developing is Windows 7 x64 and the machines that uses the app too (some x32 and some x64).
The CR references are:
CrystalDecisions.CrystalReports.Engine
CrystalDecisions.ReportSource
CrystalDecisions.Shared
CrystalDecisions.Windows.Forms
All is 13.0.2000.0 (Version) and v2.0.50727 (runtime version).
