1. Immunity Debugger

Always run Immunity Debugger as Administrator if you can.

There are generally two ways to use Immunity Debugger to debug an application:

1. Make sure the application is running, open Immunity Debugger, and then use :code:File -> Attach to attack the debugger to the running process.

2. Open Immunity Debugger, and then use :code:File -> Open to run the application.

When attaching to an application or opening an application in Immunity Debugger, the application will be paused. Click the "Run" button or press F9.

Note: If the binary you are debugging is a Windows service, you may need to restart the application via sc

sc stop SLmail
sc start SLmail

Some applications are configured to be started from the service manager and will not work unless started by service control.
