Resolution:
It is impossible to run PDriver at versions 4.x and 5.x on 64bit Engines. Attempting to do so will generate the following error:

"WARNING: PDriver-test64-0, Link Error: Task failed due to : java.lang.UnsatisfiedLinkError: LoadLibrary failure: pdriver: The specified module could not be found"

If, however, you wish to run 32bit PDriver on 64bit OS, the following steps will guide you through:

    * Install the engine as 32win.
    * Copy the PDriver components from GridServerSDK-win32/pdriver/bin
    * Deploy these to /datasynapse/webapps/livecluster/deploy/resources/win32/lib or into a win32 grid-library
