Choose the file you want to download from the right side menu.   1. Doubleclick on the downloaded file. 2. Select 'Extract To' and choose the folder of your original game. 3. Select 'Yes to All' when asked if you want to replace existing file. I strongly recommend that you turn off 'Hex Outlines' in the 'Settings' menu in the game.     So you want the more traditional Defensive Markers? Download THIS file for all Eastern Front titles. Download THIS file for all Western/Southern Front titles. ( Install as explained above. )
