chicaoterror: Hi.
I'll try to describe the best way I can.
When I open the game, the launcher shows a 404 error and Check Update doesn't work. The start screen, bottom right, shows game version 3.2 (I think it is supposed to be 5.2).
Ok, enter the game, single player and choose any American nation, the aztecs are a good example.
Choose aztec empire, beginning in october, 14, 1399. Go to Economy and research all you can in Land. The game informs you that the new "level" will be ready in the year 3000!!!
I know it is not supposed to be like this, as a friend has the same game in another store and the game is version 5.2 and the research works fine.
Really, the only thing you can research is Stability.
Strangely enough, in the GOG menus, it is showed that the game is version 5.2.
I appreciate any help.

Thanks.

mbridgham: I have the same or similar problem. Just purchased this but get a 404 error when I try to launch. I've tried the repair/verify and it appeared to load files but did not fix the problem. I would like either a fix (preferably) or a refund. I'm in Windows 10. First GOG game that did not work immediately.

fret_man: No, that link no longer works. But I found it at https://web.archive.org/web/20150211180623/http://old.paradoxplaza.com/in-game/eu3/eu3dw5_2.exe
