  • The Ultimate Collection Version (also known as the EA App version)

Versions not listed here are unofficial and are not supported by our group. It is best to only use the official versions of the game to prevent issues and to support the developers.

Step 1: Get Generals and Zero Hour

You can now buy a digital copy of all 12 Command & Conquer games from the EA App. 

Purchase the C&C Ultimate Collection via EA App.

If you already own Generals and Zero hour, skip this step.

Step 2: Install Generals and Zero Hour

Retail & TFD: Install the Game from the Discs

EA App: Install the game via the EA App Client

Step 3: Download GenPatcher and Apply Fixes
 

GenPatcher is an all-in-one application for updating Generals and Zero Hour to run correctly with Windows 10 and Windows 11.

  • It is recommended to switch off your anti-virus and real-time protection to prevent your anti-virus from interfering with GenPatcher. See why.
  • Download and launch GenPatcher.
  • Click the Apply Fixes button to apply a number of fixes to the game and get it working flawlessly on Windows 10 or Windows 11.
  • You can also install GenTool using GenPatcher (Highly Recommended).

Step 4: Borderless Fullscreen Mode (Requires GenTool)

Generals and Zero Hour regularly crash when you attempt to Alt+Tab out of the game. Enabling Borderless Fullscreen using the following instructions will make the game more stable. Note: Playing in borderless fullscreen will disable cursor edge-scrolling.

  • It is recommended to switch off your anti-virus and real-time protection to prevent your anti-virus from interfering with GenPatcher. See why.
  • Download and launch GenPatcher.
  • Go to the Additional Content tab.
  • Click on GenTool on the left.
  • Enable Borderless (fullscreen) window mode.

You should now have Generals running with borderless fullscreen, which is incredibly smooth and compatible with Alt+Tabbing. Just make sure you launch the game from the Windowed shortcut on your desktop.

GenPatcher and Anti-Virus Scanners

There is a chance GenPatcher gets flagged by your anti-virus as either a trojan or a virus. This is a false positive. GenPatcher is completely safe to use.

The reason anti-virus software may flag it is because GenPatcher applies fixes to your game's Windows registry entries, as well as moving and deleting files that could cause game instability. Therefore, to be on the safe side, the anti-virus software will block GenPatcher and prevent it from running. That's why it's recommended to switch off your anti-virus before downloading GenPatcher to ensure you won't run into any problems.

You can find more information about this on the GenPatcher support page.

Known Issues

Generals & Zero Hour Crash when Alt+Tabbing in Fullscreen Mode

If you run the game in regular fullscreen (not borderless fullscreen), the game will sometimes crash when you attempt to Alt+Tab out of it. The fix for this is to use d3d8to9-wrapper, which alleviates this issue by converting all Direct3D 8-API calls and low-level shaders to equivalent Direct3D 9 ones. Note: Do not use this if you would like to play online, as using the d3d8to9-wrapper will result in increased chances of a mismatch.

  1. Download the latest version of d3d8to9.
  2. If you also use GenTool: rename the downloaded d3d8.dll file to d3d8x.dll to make sure you don't overwrite GenTool's d3d8.dll.
  3. Place the file in the game directory of both Generals and Zero Hour.
  4. Play the game.

Zero Hour is Censored in Germany

The German version of Zero Hour is censored. To remove the censorship:

  • It is recommended to switch off your anti-virus and real-time protection to prevent your anti-virus from interfering with GenPatcher. See why.
  • Download and launch GenPatcher.
  • Go to the Additional Content section.
  • Click on German Uncut on the left.
  • Install the German Uncut mod.

Alternatively, you can download and install it manually.
