In Windows, you can use the Configuration program to sign either the default exit or a user-supplied exit, although you may also use the pr0sign program to sign either exit.
To sign an exit in Windows, you must run the Optim Configuration program. You also must run the Configuration program to switch from using the default exit to a user-supplied exit (or vice versa).
When you install Optim, you can launch the Configuration program and display the dialog used to sign an exit by selecting the Launch Optim configuration check box on the Install Complete dialog.
Before you run the Configuration program, confirm that no other Optim processes are running; if other processes are running, shut them down or wait for them to finish before you run the Configuration program.
If you want to sign a user-supplied exit, you must compile and create the load library opmexit.dll. You must then copy the DLL to the rt/bin directory before you run the Configuration program.Each time you execute the Configuration program, it checks for the existence of a signed exit. If one is not found, the Sign Optim Exit dialog displays, and you must sign either the default Optim exit or a user-supplied exit to use Optim. (See The Sign Optim Exit Dialog for further information.)

If you click Cancel without signing an exit, Optim displays a warning message and the Configuration program terminates.
