This compatibility layer enables many Windows-based applications to run on Linux operating systems, macOS, or ChromeOS.

CodeWeavers modifies the Wine source code, applies compatibility patches, adds configuration tools that are more user-friendly, automated installation scripts, and provides technical support.
