If you have anything to do with designing and desktop publishing, you must have this wonderful tool from Adobe systems. Earlier called PageMaker, Adobe InDesign is an application that you can use to create attractive designs of posters, flyers, brochures, and leaflets. It can also be used to publish content on portable devices like tablets. If you get an error message that says that Sharedcontent plugin is missing while working on Adobe InDesign, you need to download sharedcontent InDesign plugin CS5. This happens because of the fact that files in Adobe InDesign CS5 are not backwards compatible with the older versions of CS.
