You've completed your project, and you're ready to release it to the end users. How do you go about distributing it? You can choose from many ways to distribute your application, and the method that you choose depends on many factors.

You could just hand over a download link or thumb drive, scribble a few instructions, and be on your way. Or, you may want to install the application yourself—but this approach isn't always feasible. Another option is to develop an official setup program that performs the task automatically. You can write such a program in a traditional programming language, purchase a generic setup program, or write your own in VBA.

Excel incorporates technology to enable developers to sign their applications digitally. This process is designed to help end users identify the author of an application, to ensure that the project has not been altered, and to help prevent the spread of macro viruses or other potentially destructive code. To sign a project digitally, you first apply for a digital certificate from a formal certificate authority (or you can self-sign your project by creating your own digital certificate). Refer to the Help system or the Microsoft website for additional information.
