@StetoGuyYou have installed Company of Heroes in your PC and not only Eastern Front, don't you?
"Could not locate RelicCoH.exe" OR "Game is up to date" OR "Nothing Happens" when clicking playYour installation location is likely wrong, could also be directory in settings is wrong. Check these first, in order to see if your install location is good, you need to go to Company of Heroes folder and check if the "RelicCoH" app is there, along with "Eastern_Front" folder and Eastern_Front.module, you'll also see the launcher files there. If you don't see those then you installed it in the wrong place.Most common case for this is that you are using Steam Version, where it cannot auto select the install folder. Uninstall Eastern Front and then reinstall it. You must manually switch the install folder to CoH folder. Normally "C:/Program Files/Steam/Steamapps/Common/Company of Heroes" (Steam Version) or "C:/Program Files/THQ/Company of Heroes" (None-Steam Version). Remember to look at "C:/Program Files (x86)" if you use x64 OS.Remember than your install directory must end in "Company of Heroes" folder. If you add by yourself any other folder after it, the installer will proceed but the game ain't going to work.If you get "Game is up to date" and you have installed it on the right path, open EF launcher; go to Settings, then check if CoH Directory option has the correct path otherwise fix it.
