To get the latest version of Crystal for Visual Studio 2010, you need to download this from the SAP site.  Keep in mind that now Crystal does not come directly bundled with VS 2010, but requires a download.

Visual Studio 2010 comes with a template for Crystal.  You are prompted to download Crystal Reports for Visual Studio 2010 from the SAP website.  Here is the link. 

If you are installing beta 2 over a beta 1 installation, remember to uninstall beta 1.  This is accomplished by deleting the folder where beta 1 was installed.  While there currently is not a plan for a Beta 3, remember to uninstall previous versions before installing a newer one.

Currently Beta 2 includes the bits for installation with VS 2010, the runtime for 32 bit and the runtime for 64 bit.  These runtimes are large files, but Crystal is promising to reduce the footprint in time for release in November.
