I totally agree to Rob’s comment.
In addition please read the webMethods Installation guide. You’ll probably need to install at least the database components in addition, but other packages may be missing as well (e.g. WmMonitor).
WmPRT is part of the process runtime, but you need additional components for it to run properly, which are installed by following the installation guide. This will include the usage of installer and db configurator as mentioned above.
