By all means, give it a try, but do note that JuliaWin appears to be a personal project that is not officially supported. The last release was in 2022, which is quite a while ago. So, it is likely outdated.
I would recommend installing via the standard route first, before trying alternative solutions. I have no experience with JuliaWin (never heard of it), but other alternative installation methods such as brew on macOS or system package managers on Linux have been notorious for resulting in broken installations.
