L-Soft supports only the 64-bit versions of Microsoft Windows 10 and 11.  Use of the Professional or Ultimate Editions is strongly recommended; use of the Home Edition is not recommended.  Windows versions prior to Windows 10 are no longer supported by Microsoft and are therefore no longer supported by L-Soft (and please note that Microsoft support for Windows 10 ends on 14 October 2025).  Remember, however, that L-Soft strongly recommends the use of Windows Server in preference to the Workstation versions of Windows.
