To install the 2025 update correctly:

  1. Switch to the correct game version
    Enable the beta branch: steam_legacy – Pre-25th Anniversary Build in Steam.

  2. Backup your original game folder
    Copy the entire Cs 1.6 directory from Steam to a separate location.

  3. Rename system DLL file
    Rename steam_api.dll to steam_api_orig.dll.

  4. Copy NextClient files
    Paste all NextClient files into your backed-up Cs 1.6 folder.

  5. Launch using cstrike.exe
    Do not launch the game through Steam to avoid VAC interference.

Note: Only the official Steam version is supported. Pirated or cracked versions are not compatible.

You can manually configure which master server your client uses by editing:

platform\config\MasterServer.vdf
