If you have a networked version of the program you can install InfoMine on as many networked (LAN) computers as you wish (depending on system configuration and speed) all accessing central data on a designated Server which contains all your data tables. Only one computer should have data tables loaded on it. Failure to observe this will result in your data being spread across several databases without any means to consolidate them.
You should contact the vendor if you wish to setup multi user operation.
