    When trying to download Jellyfin Media Player I don't know what the difference is between the “windows-x64” and “windows-x64-legacy” versions. Under what conditions should I use one or the other?

    It depends on the CPU you have. 

    The main x64 build doesn't support CPUs without the following instructions:
    avx avx2 bmi bmi2 fma lzcnt movbe sse3 sse4 sse4.1 sse4.2 ssse3 xsave sahf mwait crc32 cx16 popcnt f16c

    The legacy version is needed for older CPUs that don't support the AVX instruction set (required for newer libMPV versions). CPUs older than circa 2012 would need to use the legacy version.
