As of Cassandra 1.0.9, the install now includes the Portfolio Manager sample application. Added new platform support (Windows 7 and Windows 2008 Server, both 32- and 64-bit) for Cassandra development. The Windows MSI installer provides a full install, including OpsCenter, sets all the WIN services, creates a Windows program group, and quickly starts the new version of DataStax OpsCenter (2.0).
Dependency on the Visual C++ 2008 runtime (32-bit). However, Windows 7 and Windows 2008 Server R2 already have it installed. If needed, download it from http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=29.
