Unzip and move the more.groupware - folder you have downloaded to C:\web\moregroupware. In C:\web\moregroupware you shall now find some folders (docs, include, modules etc.) and also the file index.php.
Now it is time to make an empty MySQL database which more.groupware can "populate" with data. Start Winmysqladmin and choose Databases. Press right mouse button inside the white databases window and choose Create Database. Give your database a name (e. g. MGW) and press Create the Database. Choose Environment and Hide me to hide away the WinMySQLadmin - window.
Start your web - browser and open the web - page http://yourPCname/moregroupware/setup/index.php. The setup is described here in full detail.
