Macaos Enterprise makes use of Windows GDI+ for graphics. GDI+ is an integrated subsystem in newer Microsoft Windows operating systems (such as XP and Vista). It is also compatible with older systems (such as 98, ME, NT and 2000) but the dll file may not be located in your search path.
Most likely, you have the file somewhere on your system already, but Windows is not able to find the file when starting Macaos Enterprise. Search your hard disk for gdiplus.dll and, if found, copy it to your Macaos Enterprise folder.
If you do not find the file on your hard disk, try downloading it from www.microsoft.com or contact Macaos Support for assistance.
