The only reason for quoting bob3160's post from February 1st 2018 is because XP SP3 and Mac OX 10.8 support ending with final LibreOffice version 5.4.5, see quote below:
Platform Compatibility
Mac
- Mac OS X version 10.8 support is deprecated and the next release will require at least Mac OS X 10.9.
Windows
- Windows XP SP3, Windows Vista SP2 are both deprecated. The 5.4 release will be the last with any support of these operating systems.
- Uwinapi is discontinued.
- Microsoft Visual C++ 2015 Redistributable is required for this release, and is not installed by LibreOffice installer (except for Windows XP). The redistributable is an OS component, that comes preinstalled with Windows 10, and with a Windows Update for Windows Vista through 8.1. If it is absent on user's system, it must be installed separately from Microsoft website. Installed redistributable's bitness (32- or 64-bit) must match LibreOffice's bitness (not OS bitness). Otherwise installation will succeed, but an error will be shown on program start: "The program cannot start because api-ms-win-crt-runtime-l1-1-0.dll is missing from your computer. Try to reinstalling the program to fix this problem".
- LibreOffice bitness is shown in Help ▸ About (for 32-bit, simply "Version: 5.4.2.2" is shown; for 64-bit, "Version: 5.4.2.2 (x64)"). It is OK to install both 32- and 64-bit redistributable on single 64-bit OS in case of doubt.

What this means is end of support for XP SP3 and Mac OX 10.8; version 6.0.1 is not supported.
