Starting in UFT 12.50, HPE has provided the UFT Runtime Engine. Here's a description of it from [HPE's UFT Help Center][1]:

> The UFTRuntime Engine enables you to
> run UFT tests (both GUI and API) and
> business process tests on your
> computer without installing the entire
> UFT IDE. In addition, you can also
> install the Runtime Engine without the
> Run Results Viewer, UFT Add-in for
> ALM, sample applications, or Help
> documentation. This can potentially
> save you valuable disk space on your
> computer.

> When you run tests with the Runtime
> Engine, you can access and run the
> test from a number of different places
> without the need to open the UFT
> interface and configure UFT options.
> When the test runs it runs in the
> background. At the end of the test
> run, you can view the test results.
