It may and it may not

First, you MUST patch to version 1.2 and you must have DX9 December 2005 or later.
Now, why it may not. Bob decided to make this mod while refusing to work with me and our groups development of the game engine. He also refused to work at removing the bugs created by the differences of the 2 versions of the PE sorce code until recently.
His hobby time is his and mine is mine, so we have no choice but to coexist like Korea.
#1 He mixed and matched at whim builds of the code so I assured him I would sue him for copywrite infringement if he did not stop including my code work in his mod. He has respected that request.
#2 The PE engine is modular. The engine bugs in PE3 are fixed by using a version of the PEx engine that addresses those engine bugs.
#3 A snot load of gamyness was removed from the PE game engine. If the data files assume this gamyness, your simulation experiance will be ruined. Bob's latest release went from physics of an extream to deal with the original PE engine to the opposit extream to negate the limitations of the new engine. It's not perfect, but at least he made an effort.
#4 The PEx game engine will not run on video cards that do not support hardware vertex procesing (ie most laptops). This seems to be fixed in version 16.12.2, but that version is still in internal testing.
I don't hide in multiple forums, using multiple names, like some. I am happy to answer any question, but I am not a profesional developer so my answers are limited by my knowledge.

most here know I am a nerotic jerk.
