are you using a combo of disc and download? If so you still need the disc to play. Your game should be patched to 1.67.
have you downloaded Origin? You need orgin to play and patch the game. This is for PC but if you need Mac scroll down to the Mac Link.
https://www.origin.com/en-us/download
If you already have origin installed and the game is not patching to 1.67 try the superpatchcher. has links for both PC and Mac
thanks for replying. My base game is patched to 1.67. However, I could only patch ambitions to 4.5 because there was a downloading error on patch 4.6. I'm still not sure though why it wont work. I bought both games, base game and ambitions through origin via pc download. they both installed fine. It's just now when I try to click my base game to play ambitions, the game will not launch. the launcher disappears but nothing happens. Is there anything else that could be causing this problem? Any and all help will be greatly appreciated.
Now that we have origin you don't need to patch any EP's only that the base game is patched to 1.67.. Were you trying to patch ambitions manually? If so you don't need to do that. This maybe your problem.
Scroll down to the bottom of the web it will tell you how to uninstall ambitions only manually

Then do a clean install and dont patch ambitions.
I will try it and let you know how it goes. Thanks for your help. 😕mileyhappy:
