If you developed a database using 4D's Web Assistant on a Windows computer, and wish to server this database on a different Windows computer, simply moving the database files over to the new Windows machine will not work. All the changes made to the database using the Web Assistant are not stored in the structure file, but in the Web Assistant preferences. Therefore, if you have developed a database on a Windows computer and wish to serve it on another Windows computer, you will have to move the database files as well as the Web Assistant database preferences, which are located in the "4DWebAssistant" folder.
