Do not install “Company of Heroes” before installing the “Opposing Fronts” expansion. “Opposing Fronts” has “Company of Heroes” built-in. However, you still have to download “Company of Heroes-LOADiNG”, as you will need it, to install both games. If you already have “Company of Heroes” installed. Backup any saved games and uninstall it – including removing any “CoH” or “OF” folders in “My Documents” (doing so is the only way to make sure the patches to be installed, will see your installation as valid).
Also make sure to uncheck the default checked option on the installer, causing the game to run directly after installation. Doing so is the fastest way to patch the game, but it still may take some time… Head over to the directory where you installed “Opposing Fronts”, and under “validators”. Now here comes the tricky part. Find a crack that matches the latest patch you downloaded (if the latest patch is new, you might have to wait a few days for a crack to be released). The only hint I can provide is “GCW”. Again, head over to the directory where you installed “Opposing Fronts” and backup the file “RelicCOH. You might receive a dialog saying “please insert disc” during various parts of the game. But in any case, the dialog will be just as pleased by you pressing the “Continue” button. When the in-game selection menu, click on any locked “Campaign” and enter the serial.Heroes-LOADiNG” release. When asked where the purchase was made, select “Retail Store”. -You should now have both games fully patched. Enjoy!
