Commandos: Behind Enemy Lines is a singleplayer and multiplayer bird's-eye view and isometric stealth and strategy game in the Commandos series.

The game has significant issues on modern systems out-of-the-box. In Windows 10 and newer, the internal compatibility library is assigned to a misspelled executable name (commandos.exe instead of comandos.exe), so the executable needs to be renamed to function properly and pass the DirectX 5 check on startup (already applied in the Zoom Platform release). Issues with game speed have several workarounds in the Essential improvements section of the article as well. Additionally, the retail version's installer is a 16-bit application and can not run on 64-bit systems; see Issues fixed for a workaround.

Disc check (requires the CD/DVD in the drive to play)
Illegal Table of Contents and oversized DRM (lead-out area shortened and used for data, to prevent most contemporary CD-RW drives from copying the method)
Ammo Pack retail release. The game might ask for the disc (depending on the game's registry values), however it's nonfunctional and can be ignored by selecting cancel.

Version differences

The and Zoom Platform versions have added compatibility fixes for modern systems.
The version includes Commandos: Beyond the Call of Duty, and is cheaper than buying both games separately on Steam.
The Zoom Platform release has assets fully extracted instead of bundled within <path-to-game>\WARGAME.dir.

Essential improvements

Skip intro videos

Delete/rename H_Intro.avi[citation needed]
  1. Go to <path-to-game>\VIDEO.
  2. Delete or rename H_Intro.avi.


The latest official patch for the European retail release is 1.1. The US release is already patched.

Remove CD check

Only applies to the DRM-free Ammo Pack retail release. Do NOT use for DRM-protected releases.
Edit the registry keys

If installed manually:

  • At step 3 of the manual installation fix here, for the DirCd value, use the same path as DirIns.

If installed using the game's installer:

  1. Copy the VIDEO folder from the disc to <path-to-game>.
  2. In Windows Registry navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Pyro\Commandos\1.0.
  3. Change DirCd's path to the same one as DirIns.

Stability and speed fixing

The game is intended to run at 15-20 FPS as animations and game speed are tied to framerate. Increasing this will make the some missions needlessly difficult. Modern systems tend to run the game at a higher speed than they are supposed to.
Method 1: DDrawCompat
  1. Download DDrawCompat and extract it to <path-to-game> (use the Legacy subfolder if using the Steam version).
  2. Rename comandos.exe to commandos.exe if running Windows 10 or newer to pass the DirectX 5 check on startup (do the same in the Legacy subfolder if using the Steam version).
Method 2: DxWnd
Allows game to be run in windowed mode, without the mouse freezing / game speed up issue and ingame sound.
  1. Download DxWnd and extract it to an easily accessible location.
  2. Rename comandos.exe to commandos.exe if running Windows 10 or newer to pass the DirectX 5 check on startup (do the same in the Legacy subfolder if using the Steam version).
  3. Open DxWnd
  4. Under the "options" tab, select "expert mode".
  5. Under the "edit" tab, select "add".
  6. Within "main", select the path and launch to be the newly renamed executable file (use the Legacy subfolder if using the Steam version).
  7. Optionally, change the window size settings to desired values (note that too high resolutions can cause graphical issues due to limited map sizes early in the campaign).
  8. Up the top of DxWnd select the "Video" tab
  9. Deselect "Emulate Win Maximise" within window handling
  10. Check "Locked Size" within windows size and position
  11. Up the top of DxWnd select the "Msgs" tab
  12. Check "Swallow mouse move messages" within message handling
Method 3: Steam Ultimate fix[2]
Fixes many of the numerous bugs the Steam version has (lack of sound, not being able to save or load and the gameplay running incredibly fast)
  1. Download the patch and extract it to <path-to-game> (use the Legacy subfolder if using the Steam version).
  2. Rename comandos.exe to commandos.exe if running Windows 10 or newer to pass the DirectX 5 check on startup (do the same in the Legacy subfolder if using the Steam version).

Issues fixed

Can't install original retail version on 64-bit Windows

Manually install the game[3]
  1. Create the game's directory (the default path is C:\Program Files (x86)\Eidos Interactive\Pyro\Commandos)
  2. Open the <cd drive>\COMANDOS folder and copy its content inside the first folder
  3. Open a text editor, save the following in a file with the .reg extension, then open and apply it.
Windows Registry Editor Version 5.00



"DirIns"="C:\\Program Files (x86)\\Eidos Interactive\\Pyro\\Commandos"


The above .reg file assumes D: as the CD drive and the default game path as the installation folder. Adjust these registry keys accordingly.
On 32-bit Windows, omit Wow6432Node from the path.

Save and load are disabled

This issue occurs if you install the game manually (by copying over the game files), but not create the registry keys.
Create the registry keys mentioned in the manual installation fix here.

"Please run the German version on this computer" error

This issue has been fixed in the version (specifically using the hex edit below).
Change your Windows language setting from "Deutsch (Deutschland)" to "Deutsch (Luxemburg)"[citation needed]
Hex edit Comandos.exe[4]
  1. Open the game executable with a hex editor such as HxD.
  2. Search for 74 0C 81 FE 07 14 00 00 74 04
  3. Replace first and last 2 groups of byte (74 0C and 74 04) with 90 90
  4. Search for 74 0C 81 FF 07 14 00 00 0F 85
  5. Replace 74 0C with 90 90 and 0F 85 with 90 E9


This occurs due to the internal compatibility database within Windows 10/11 being assigned to the wrong (mistyped) filename.
Rename comandos.exe to commandos.exe[5]


Already applied in the Zoom Platform release.

Black screen error

This occurs due to the lack of VP6F codecs in modern operating systems.
Move, delete or rename the Video folder.[citation needed]

Game stutters when moving the mouse

Mouse movement seems to be tied to frame rate which can cause the game to stutter only when the cursor is moved
Change your mouse polling rate to 125 using its software. If no software is available, try using a different mouse (cheap mice work better) or use any Bluetooth mouse to play the game.
