So, I have a EUR copy of the SC4 DLX but I am and wish to build Amercian style cities. The first thing I did after installing the game on my new PC build (I had it on my old one for over 6 years) is go into regedit and change language to 01. When I did this years ago I had no issue. This time the language pack does not display correctly for in game tooltips, advice columns and even querries. I attempted to reinstall and that did not solve the problem. Any help would be immensely appreciated folks.
I have answered this question in your thread over at Simtropolis.
