Fly Swatter.... The performance visuals for ETO file is very easily set to install into a 64 bit system. Download the eto-Perf_visuals.exe file (click open and extract it to a location on your PC (desktop for example) There will be three files... a text document with instructions, a folder with configuration settings, and an .exe that installs the files to your game folder., double click the .exe file to run the installer, the first screen you will see is the location to extract files into confirmation page. Click the browse button and browse to your ETO installation folder (should be C:/program files (x86)/microsoft games/CFS3 ETO Expansion) and select or type the location..... click install and let it run. If it asks to overwrite files select yes ( a full set of backups is provided in case you want to go back to the original settings). Then open the configuration settings folder, it walks you thru the cfs3 configuration page by page, follow the instructions. When you finish that, go to your ETO folder, C:/program files (x86)/microsoft games/CFS3 Eto Expansion and open the Terrains folder, at the bottom of the list find the scenery.zx and terrain.zx files and delete them (it writes new ones when you restart the game).
Thats it....enjoy...
