Enhancements and updates in the source code support the special requirements of those operating systems. These changes also affect customization handling, i.e. plug-ins and the COM API.
The newer operating systems are more restrictive than earlier operating systems with respect to user access to system files. In particular, regular users generally cannot modify the content of the WINDOWS and Program Files directories. Therefore, FORMS now supports customizable file locations. For example, the location of the Ehlocal.ini file is no longer hard-coded to C:\WINDOWS but can be specified during installation.
