Cannot find Crystal Decisions Engine

[pwl2706]

hi,

I have Visual Studio 2010, targeting .NET Framework 2.0 (that's set in Project Advanced Compilation options).

I have Crystal Reports 10 installed.

but this folder that was in the references for the project (was originally on another pc) I am working on is not found:

C:\Program Files\Common Files\Business Objects\2.7\Managed folder

what version of Crystal Reports will give me the tools I need?

thanks
Philip
