The first step would be to keep it on a drive that is not shared. That will
keep it out of the hands of anyone who doesn't have access to the computer.

Second step is to control who has access to the computer.

Employ armed guards as needed.

Can anyone tell me how to limit the use of a workbook to a single
computer. I
want to prevent anyone from using a workbook on more than 1 computer. Is
there some way to do this?

Thank You,
Dick
