To create a new database, or to connect to an existing database you must first run the Axosoft App Configuration utility.
You should be able to open the Axosoft App Configuration utility from the "Start Menu->All Programs->Axosoft->2019->App Configuration->Axosoft 2017 App Configuration".
This utility is normally installed in "C:\Program Files(x86)\Axosoft\2019\App Configuration" directory and has the filename "AxosoftConfig.exe".
This desktop utility will allow an Axosoft Administrator to configure the system.
After you set up your database connection using the above utility, reload this page to log in. There is a built-in account called "Admin".
By default the Admin password is blank (empty).
After logging in as Admin, be sure to change the Admin password to prevent other users from gaining control of your installation.
