You can install LibreOffice in parallel with OpenOffice. If you imagine of “full ‘Transition Heading’” as some kind of universal guide to “what is not needed”, then it’s impossible thing. There is the installation guide linked from download page there’s finite amount of what is needed, and infinite amount of what is not needed. Generally, your questions fall into the category of “this is not needed that is not needed…”. Multiple MSVC versions happily co-exist on the same system, so no need to uninstall one before installing LibreOffice.Anyway, you need not worry about that - it will be handled by installer. You didn’t need two MSVC packages for your OpenOffice (only 32-bit one was required, and it was installed automatically), although other programs on your system could require other MSVC versions and architectures. It was that way 10 years ago, and it’s still the same today. Required version of MSVC is always part of the installer bundle.And if you use the solver, you still need JRE. Java is not needed for spreadsheets - and wasn’t needed for OpenOffice Calc, too - except for solver component.Uninstalling OpenOffice does not affect any files kept outside of its installation directory so unless you did a very strange thing - kept your ODTs and ODSs in the C:\Program Files (X86)\OpenOffice, - you are safe.They don’t conflict with each other (except for trying to associate themselves with the same types of files, which doesn’t break things, and only affects which app is launched when you double-click your ODT). You may uninstall OpenOffice before installing LibreOffice or you may do it after or you may choose to not uninstall it, and keep both.There’s no need for all the worries that you expressed in the question.
