The Add ORMM add-in allows the user to install and remove add-ins in the ORMM collection without using the Add-in command of the Tools menu. With the add-in installed, OR_MM appears on the Excel menu as shown to the left. Selecting the Add ORMM item presents the dialog below. When the check box adjacent to a title is selected the add-in is installed. When a check is removed, the add-in is removed and the associated items on the ORMM menu are deleted. If an entry on the list has a gray color, the associated add-in cannot be located.

The dialog shows all the ORMM add-ins that are in the same folder or directory as the Add ORMM add-in. The Scan button causes a search of that directory.

To install the Add ORMM add-in, choose the Add-in command on the Tools menu. Browse to find the directory where the add-in is stored and double click on it. Once installed, the ORMM menu remains on the main menu bar of Excel. This makes the entire ORMM collection of add-ins immediately available. For more instructions on installing and using add-ins see the Using Add-ins section.

The OMIE button on the dialog installs the Add OMIE add-in for access to the add-ins in the OM/IE collection. The Teach button installs the Add Teach add-in for access to the add-ins in the Teach OR collection.

The Demos command button presents the dialog below. The buttons refer to Excel workbooks that demonstrate features of the add-ins. By clicking the buttons on this dialog one or more of these workbooks will be opened. This makes it easy for the student to review instructions while working with the examples on an active workbook. The workbooks are opened after the ORMM dialog is dismissed.
