To install the 97-99 updates, from the CD simply select the 97-99 option; if running from the web or E-mail, run ADV9799.EXE (requires a password - if you do not have it call us at 888-923-3786 or send an E-mail to firstname.lastname@example.org).
This installation will automatically run an install program that will launch the Advanced Accounting engine. When you see your license, simply press the ENTER key and allow the process to complete.
Generally you would only install the ADV9799.EXE file if you have never previously installed any updates since purchasing Advanced Accounting. The updates must be installed in order (except for payroll 2001).
