When installing and running UltraBac the first time, logon using an Administrator's ID.
Run the UltraBac program "UB.EXE". The first time this program is run it will automatically create a new entry in Control Panel's Services for the BEI Scheduler Service and the "Scheduler Service Installation" dialog box will be displayed prompting the administrator to enter a User Name and Password. This is required in-order to schedule backups. If the user ID entered into the dialog box already exists, it will be validated against those on file. If the user ID does not exist, it will be dynamically created.
Note: If the "Scheduler Service Installation" dialog box does not automatically come up when UltraBac is started and the BEI Scheduler is not installed then make sure to select the "Tools"/"Preferences"/"Advanced"/"Enable Scheduler Service Installation Dialog" option and then restart UltraBac.
