On the Tools menu, click Import Project.
This option creates a new project from a BuildPlus import file (.bpi), as created with Export Project.
You will need to enter the location of the import file, the BuildRoot to create the project in, and a name for the project.
If the project that was exported used UNC paths (eg \\datacomputer\sharedfolder), then you should be able to build the new project without any problems by opening it and clicking the Build button.
