Which version of julia-nightly is for which Windows version appropriate?  
is the julia-nightly-64-bit-version for Windows 64.  
I ask, because the julia-nightly-32-bit-version errors with a  
Tree Hash MisMatch Error when compiling.

If you are using juliaup maybe you ran into this:

> [@Julia v1.11.7 has been released](https://discourse.julialang.org/t/julia-v1-11-7-has-been-released/132437/1):
>
> Apologies to anybody who ran into issues yesterday; the permissions on the binaries were initially set incorrectly, which cascaded through the multi-step release process in a way that wasn’t visible until the end, leaving things in a weird state. We’ll be working to make the overall process more robust to avoid disruptions in the future.

In that case just update again.

I just create a self-contained demonstration here:

Cool. It works and added everything that was missing to PATH. Only Line 39 in your script (step 5) didn’t succeed programmatically:

> IOError: could not spawn `juliac multiply_numbers --output-exe multiply_numbers.exe --bundle build --trim`: no such file or directory (ENOENT)

I ran this command directly using the cmd and it worked.  
Thank you very much. I wished to see such examples of juliac use!
