Official packaging for Windows do not include Python dependencies for lldb

[nedsociety]

• Running on Windows 19044.2006 (x64)
• lldb downloaded from https://github.com/llvm/llvm-project/releases/download/llvmorg-15.0.1/LLVM-15.0.1-win32.exe

Running lldb yields following error (0xc000007b = STATUS_INVALID_IMAGE_FORMAT)

If I run LLDB from the official release it complains about python310.dll not found (I don't have Python 3.10 installed on my system). I suspect that you do have Python 3.10 installed and included in PATH, but it is a 64-bit install. Since you are trying to run a 32-bit build of lldb, it cannot load the 64-bit python310.dll, hence the STATUS_INVALID_IMAGE_FORMAT error.

The quick fix for you would be to download "Windows embeddable package (32-bit)" from https://www.python.org/downloads/release/python-3102/ and extract it next to lldb.exe. I don't know if there are anything that can be done by LLDB to handle this better.

The situation looks exactly as what you've described. I'll change the title.
