This command is necessary
when working with a worksheet created by another computer.
It creates new buttons that are linked to the active add-in.
If the buttons on a worksheet do not work or result in an error
message, click this botton. It causes the buttons on the worksheet
to be erased and new buttons created.
The Math Programming add-in constructs the math programming
model and the Solver add-in solves the model, so
those two add-ins must be installed in addition to the Equity add-in.
Before attempting to create a model, choose the Solver command
from the Tools menu. This opens the Solver dialog.
Then immediately close the dialog. This establishes contact
with the Solver. This step must be performed
every time Excel is launched.
