I need to reinstall CMSF and one (or more) modules. How do I do that?

If you have a CMSF module, then you do not need your base game license key (ever again). That's because when you activate a module with a module license key, the base game is activated automatically as well. There is no need to license the base game separately if you intend to install a module with it. For Windows Vista and Windows 7 users we recommend running the installers by right-clicking and selecting "Run as administrator" from the popup menu. The default directory for Battlefront versions is usually '\Program Files\Battlefront\Combat Mission Shock Force' for 32-bit versions of Windows and '\Program Files (x86)\Battlefront\Combat Mission Shock Force' for 64-bit versions of Windows. Please double-check where you install the game and ensure that modules and patches install to the appropriate directory. A new folder/directory in the game's actual directory would be an incorrect location to install a patch to. Most patches will replace the main game executable and you should get confirmation that the patch installed properly by looking for this version number at the bottom, middle of the main menu screen. Here is the correct way to reinstall CMSF and its modules (as of patch v. 1.32): - Install CMSF, do NOT license it if it is a Battlefront version. - Install the v. 1.10 patch for your distribution (Battlefront or Paradox). This step is sometimes not needed if you have the Marines module, but bundles that include the Marines module may not have all of the necessary files that are part of the v. 1.10 patch. - If you have the Marines module, install it now. - If you have the Marines module, launch CMSF and use the Marines license key to activate (this activates both CMSF and the Marines module). - If you have the British Forces module, install it now. - If you have the British Forces module, launch CMSF and use the British Forces license key to activate it now. - Install the v. 1.21 patch. Make sure to make the correct selections for the modules you have. Making an incorrect selection will result in modules disappearing or license key requests for modules you do not have. If you run into this problem reinstall the v. 1.21 patch again and make the correct selections. You must install the v. 1.21 patch BEFORE installing the NATO module. - If you have the NATO module, install it now. - If you have the NATO module, launch CMSF and use the NATO license key to activate it now. - Install the v. 1.31 patch. Make sure to make the correct selections for the modules you have. Making an incorrect selection will result in modules disappearing or license key requests for modules you do not have. If you run into this problem reinstall the v. 1.31 patch again and make the correct selections. - Install the v. 1.32 patch. Make sure to make the correct selections for the modules you have. Making an incorrect selection will result in modules disappearing or license key requests for modules you do not have. If you run into this problem reinstall the v. 1.32 patch again and make the correct selections.
