Canon has posted updates for almost all of the Mac and Windows applications it bundles with its line of digital SLR models, and has also released Canon RAW Codec 1.0 for Windows Vista.
Digital Photo Professional 3.0, EOS Utility 2.0 and ImageBrowser 5.8b/ZoomBrowser EX 5.8b updaters, as well as the full installer for RAW Codec 1.0, can be downloaded from any of the recent-model Canon digital SLR pages on Canon's Web Self-Service System website, including via the Drivers / Software
link on the Canon EOS 30D page
. For the updaters to run, you must have earlier Canon digital SLR software installed.
