I've uploaded a new version of the Unreal port here:
Workupload
Be aware it deviates from the original game a bit, it now supports buying more arenas (starts at 100k and increases in price by 50k with each purchase) because that was bottlenecking progress, it keeps track of the last selected worker in the reception when switching to different pages, and I added a button to automatically assign the most profitable clients to workers who aren't doing anything. I also tweaked the default client pool to have an easier mix of sizes and relaxed restrictions for sizes workers will accept, and allowed the number of clients to scale with more workers so you don't run out of clients as easily with over 100 workers.
You have to have the original game installed and you install the paccs for that as normal, then when you first run the Unreal version you have to go to options from the main menu and "Choose Pacc Path" and point it to a directory inside where you installed the original game to so it knows where to get the data from. It just uses the data from the original game so you need to keep the original game around.
