Yes. If you purchase the single-ministry license (click here for pricing), you are allowed to install the program on multiple computers providing that all the computers are supporting the same ministry/department within your church or organization.
For example, if you are registering Envision for use with your youth minsitry, your license allows you to install copies on as many computers as you like, as long as you are using all the copies for your youth ministry.
You'll need a special code to install the program on additional computers. All you need to do is e-mail us and let us know what you need, and we'll send you the code right away!
