Things You'll Need
Instructions
Download a No-CD Crack that is patched to your current version of the game. These cracks are available from a variety of file-hosting sites, such as GameBurnWorld, GameCopyWorld, or The Pirate Bay (see Resources). Once downloaded, the files will be a compressed folder.
Unzip the files with the file extraction program of your choice, such as ExtractNow, WinZip or WinRAR. To extract the files, right-click the compressed folder, click "Extract..." or "Archive..." and choose where to extract the files. Any location will be fine for now.
Open the extracted folder and copy the file "ArmA II.exe" by right-clicking the file and clicking "Copy."
Replace the current "ArmA II.exe" file in the "ArmA II" directory by pasting the new version of the file into the folder. The "ArmA II" folder can be located in a variety of places, depending on where you instructed the game's files to be placed during the installation process, but the folder is located in "Program Files" by default.
