Xpert-Timer runs on Windows 10, Windows 8, Windows 7, Windows Vista and on Windows Server 2008, 2012 and 2014 (incl. Small Business Server).
Xpert-Timer Basic includes an SQLite database for single users, Xpert-Timer Pro a Microsoft Access database for single users and a Microsoft Access database formulti users. We suggest to use the Access database with a maximum of 3 users. If you plan on running Xpert-Timer with more users, you should install a MySQL server or MS-SQL Server. The free Express Version of MS-SQL 2014 or 2012 is perfectly fine and the free version of MySQL5, too.
