The final step is to register the Solver add-in with 1-2-3 97 Edition. To do this, start 1-2-3 and select the Add-Ins option from the File menu. Then select Manage Add-Ins... from the cascading submenu. A dialog box should appear, containing a list of add-ins (which may be empty). You will add the Solver add-in to this list, and specify that it should be auto-loaded.
Click on the Register... button. In the Register Add-In dialog, which operates like a File Open dialog, navigate to the directory containing solver.12a (normally c:\lotus\123\solver). Click on solver.12a in the file list, then click on the Open button.
The Manage Add-Ins dialog should reappear, this time listing the Solver add-in's path, such as c:\lotus\123\solver\solver.12a. Now click just to the left of the drive letter on this line, so that a check mark appears next to the full pathname. Then click on the Done button.
To verify that the Solver add-in has been registered, select the Analyze option from the Range menu. On the cascading submenu, you should see a new Solver... option. You select this menu option to activate the Solver and display the Solver Parameters dialog.
Now you can open solvsamp.123, which should be in the directory c:\lotus\123\solver, and try out the six Solver examples on tabs B through G of this workbook. You can also set up and solve a problem manually as described step-by-step in sheet tab A.
