Ira Brown returned to discuss using multiple versions of Project on a single computer, starting with the proper way to install Microsoft Project 2010. One correct method of installation is upgrading from a previous version (such as Project 2007) to Project 2010. The second way allows users to run both Microsoft Project 2007 or 2003 and Microsoft Project 2010, as seen in the video on compatibility.
Ira showed how to updateglobal objects so that features such as macros will carry over from an older version to Microsoft Project 2010. He also pointed out differences between Project 2007 and Project 2010. Although this was already covered in the compatibility video, he showed how to save files so that they can be opened in an older version of Project. If a project file is created in Project 2007 or older, Project 2010 can open it in backward compatibility mode. However, that means that some new Project 2010 features will not be available.
Problems arise when a project file is created in Project 2010 and then a user tries to open it in Project 2007. To do this, the user must save the project file of the version intended to be used in the future. In other words, to use a file in Project 2007, save it in Project 2007 format even if you are currently using it in Project 2010. Project 2010 also includes an option to save a file for sharing. This allows a user using Project Server to share the file with a user running a standalone Microsoft Project.
This is a great video both for users who have just started using Microsoft Project 2010 and those who are using two different versions of Microsoft Project.
