There are already Bitcrack binaries available for Windows that can be ran standalone. They can be downloaded at https://github.com/brichard19/BitCrack/releases/tag/0.31. Which one you use depends on what GPU you have. NVIDIA gpus can use cuBitCrack.exe or clBitCrack.exe, while other gpus can only use clBitcrack.exe.

AddrGen doesn't require a GPU and can always be ran. It just generates a bitcoin address and public/private key.
