Before installing
Use Windows 10 or 11 64-bit, keep at least 500 MB free and close older BAS setup programs.
Help Center
Install BAS on Windows 10 or 11
Use only the installer linked from the official Download page. Windows may show a SmartScreen prompt for a newly distributed application.
Windows SmartScreen
Confirm the file came from businessaccountingsoft.com. If Windows displays a protection prompt, open More info, verify the application name and continue only when the file is the expected official installer.
Updates and removal
Back up business data before major updates. Removing the application does not replace the need for a verified backup.
