The application writes to a MDX database file in the "SCREENS" folder inside the installation folder. This may also prevent operation on Terminal Server, or Fast User Switching.

Further, the Windows Installer-based installer does not support silent, passive or Group Policy-based installation.


As an administrator, grant Modify permissions to the BULTIN\Users local group for the following folder:

%programfiles%\Newmarket International\Delphi\SCREENS

Example command line:
cacls "%programfiles%\Newmarket International\Delphi\SCREENS" /e /t /g Users:c

Also watch usage on Terminal Server, or on Windows 7 with User Account Control enabled, as each user may end up with their own delphi.mac and delphi.mdx files. This should not affect shared usage as long as the database and shared files folder is on a network server that the user has Modify access to.
