Technical information

These information is based on the trial version of the Trygames release.


The Installer is a Wise installer.

  • Most of the audio files in the archive are in .OGG format in order to reduce the installer size, as well as /User/Import/logo2.bmp.jp2 . These files are decoded using a special program called decoder.exe during installation.
  • The installer logs installation process in a temp file, and later converts to INSTALL.LOG after installation.

The installer does the following:

  1. Extracts the uninstaller "UNWISE32.EXE" from the archive to <APPDIR>\UNWISE.exe[1] ; also makes an entry for Add/Remove programs.
  2. Extract all the files from the archive to <APPDIR>.
  3. Launches decoder.exe -f lfiles.lsy -p to decode the .OGG sounds and the .JP2 image.
  4. Deletes the following files (in order)[2]:
    • lfiles.lsy
    • Xjp2.dll
    • libgfl170.dll
    • decoder.exe
  5. Adds links to its group in the start menu[3] (in order):
  6. Writes the following to the registry (in order):
    [HKEY_LOCAL_MACHINE\SOFTWARE\Team17 Software Ltd.\Worms Armageddon\1.00.000]
    "CD Tracks"=dword:0000007f
    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\WA.exe]
  7. Prompts and adds a desktop shortcut to Worms Armageddon.
  8. Advises user to install the Beta 2 update if Windows XP/2000 is detected.[4] Clicking "Yes" launches the browser to download the update from Trymedia:
  9. Activates the Trymedia DRM by writing the following to the registry (in order)[2]:
    [HKEY_LOCAL_MACHINE\SOFTWARE\Trymedia Systems\ActiveMARK Software\90E9B1D2C4C85AE675F1822345339973]
  10. Deletes "<APPDIR>\bbytdll.dll"[2]
  11. Converts the temporary log file to <APPDIR>\INSTALL.LOG .


  1. By default, the installer chooses "%Program Files%\Team17\Worms Armageddon\" as the installation directory. For the purposes of this article, <APPDIR> refers to the installation directory chosen by the user, as a string.
  2. 2.0 2.1 2.2 This process is not logged into INSTALL.LOG . Beware.
  3. By default the group name is "Team17\Worms Armageddon"
  4. The message is: "The program are you trying to install was not designed for your operating system. The program may not work properly. Press YES if you want to download a patch for Windows XP/2000 or NO to finish the installation process."
