This hotfix for Arma 2: Operation Arrowhead resolves a few issues with the original Windows 11 update and brings a quality-of-life change to the branch configuration.

We are adding the new Windows 10 and 11 compatible BattlEye files to Arma 2 OA's /Expansion folder to ensure functionality with older setups.

We are also removing password protection from the branch 163_backup which contains 1.63 version of Arma 2 OA. This is to ensure compatibility with Linux servers still running on the 1.63 version.

Changelog
