Windows 7 or newer is required. The compiled executable can only run on the system where
it was built.
cpuminer-opt-24.7 adds support for ARM CPUs with Windows 11 with some changes in build procedure noted below.
#### Install MSYS2
Download and install the latest version of msys2-x86_64 from https://www.msys2.org/.
Update packages and install mingw toolchain but leave the MSYS2 MSYS window open at the end to install
more packages in the next step.
The Mingw toolchain for ARM does not yet support GCC so use CLANG Instead on ARM CPUs.
The Msys installer for x86 can also be used to install MSys correctly on ARM CPUs.

#### Download cpuminer-opt
Download and decompress cpuminer-opt source code. Download the tar.gz file as it preserves file permissions, specifically executability. It can be dowloaded from the Windows web browser or from MSYS2 MinGW-w64 terminal. This is different from the terminal used for package installation.

If Windows tools are preferred cpuminer-opt can be downloaded to the Windows Documents folder and accessed from MSYS2 MinGW-w64 terminal using the path /c/users/[USER]/documents. Notepad++ and 7zip are useful Windows programs with good support for Linux file formats. The MSYS2 home directory can be accessed from Windows with C:\msys2\home\[USER].
Cpuminer-opt can be downloaded from the MSYS2 terminal using git or wget. Git will download the most recent source code, it matches the latest release.
