What does Runtime Program mean?
A runtime program is a specific version of an application that is distributed for limited use. These kinds of software releases may be called runtime programs because they offer a runtime environment without other features that allow for more permanent use, such as building executable files.
Techopedia explains Runtime Program
A runtime version of a piece of software may be made in order to facilitate free distribution for testing, developer education or other uses. The maker of the software may still demand a license fee or require licensing for these limited versions, but in many cases, runtime programs are distributed freely to specifically designated recipients.
Another use of a runtime program is in order to allow developers to execute programs that are made for a specific application, such as a programming studio. Many think of these types of programs as provisional programs. Those who use a runtime program may need considerable programming skills in order to build aspects of a piece of software from scratch or calibrate a runtime program effectively.
