BusinessMan is a complete solution which has other file dependencies, as is the case with most programs you use. If your computer does not contain these dependant files, BusinessMan will try to install them as quickly as possible. Once installed, you will not need to install the files again. After installation, the next time you run BusinessMan you will be able to log in without any prompts.
These files consist of plug-ins and images which enhance the functionality of BusinessMan and can be found in the FileMaker installation directory (of the BusinessMan directory if using a run-time).
