From Stand By Soft:
RationalPlan Project Viewer by Stand By Soft is a free project management software viewer, the perfect solution for anyone (from project stakeholders to team workers) to view your projects in detail. Although the project managers plan and control the projects from start to end and make all the necessary changes, there are some other people, the stakeholders that need to check and overview the projects evolution into their smallest detail. RationalPlan Project Viewer is freely distributed as a viewer for our products. Besides it gives you the possibility to import MS Project files and to view them also for free. That makes RationalPlan Project Viewer a free project viewer for both RationalPlan and for MS Project.
