No. If you install or update the Folio Producer tools in either InDesign CS5 or InDesign CS5.5, the Content Bundler is disabled. If you still need to use the Content Bundler to create folios for a custom viewer app, finish your production work before installing the new tools, or install the new tools on a different computer.
If you install the Folio Producer and need to use the Content Bundler again on that computer, uninstall the version of InDesign in which the Folio Producer tools have been added.
The Folio Producer tools for both InDesign CS5 and InDesign CS5.5 are available for download here:
