This is slightly off the topic . . . .
Is there any reason[s] why you have not upgraded to the free version of 
Win10 [Home or Pro]?
Or, are you satisfied with the tiled desktop in Win8.1?
Although Win10 does have its issues, same with Win8.x, it does have the 
tiles in the new version of its "Start Menu".
---------
As for the install issue[s]. . . .
You should go to the "Programs and Features" section of the Control 
Panel and try to uninstall an version of LibreOffice that is listed.
Then deal with the removal/renaming of the LibreOffice folders for both 
4.4.x and 5.0.x [at main  folder level] that hold the User Profile and 
all the other info/files there.  This link will point you in the correct 
area of the system folder[s] where the LibreOffice folders are located.

Restart the computer.
Then download a new install file - 4.4.5 or the 5.0.x version. Install 
LibreOffice again.
This should give you a clean, and working, install of LibreOffice.
This process has worked for me with XP, Vista, and Win7.
I have no Win 8.x systems.
I am installing Win10 on most of my Win7 systems, when I have time and 
can dig the "spare systems" out of under-counter storage and set it up 
somewhere there is space of another system.

I had my laptop computer (Toshiba Satellite L55-B5276; Windows 8.1)
repaired, and when I got it back, I found that my LibreOffice (4.4.4) could
not be used. I got a message:
==========
LibreOffice 4.4.4  -- Fatal Error
---------------------------------------------------
The program cannot be started.
The service manager is not available.
("premature end of file:///C:/Users/
Taang/AppData/Roaming/LibreOffice/4/user/uno_packages/cache/registry/com.sun.star.comp.deployment.component.PackageRegistryBackend/commom.rdb")
Start setup application to repair indtallation from CD, or the folder
containing the installation packages.
[OK]
==========
I did not understand what the message meant.
Thinking that I could repair it, I went to the folder where I saved the
program, and I clicked the program twice.   When the the time came for
installation, I clicked "repair",  and it was successfully installed. But
when I clicked LibreOffice 4.4.4 twice,  the same message appeared.
Every time I clicked LibreOffice 4.4.5,  5.0.0 and 5.0.1, I got the same
message, except for the heading, which changed to
LibreOffice 4.4.5  -- Fatal Error
LibreOffice 5.0.0  -- Fatal Error
LibreOffice 5.0..1 -- Fatal Error
How can I use my LibreOffice again? What do I need to do?
Sincerely,
Taang Zomi
