LiberOffice fails to install

64-bit Dell

Existing working version of LO: 5.1.6.2, I believe it’s 32 bit.

When attempting to install later versions 5.3.6 64-bit and also previous version 5.2.7 32-bit, after progressing through the early dialogs and then clicking ‘Install’ from the ‘Ready To Install’ dialog, I immediately get an ‘Installation Wizard Completed’ dialog with the message ‘The wizard was interrupted before LO 5.3.6.1 could be completely installed.’

What is happening and how do I fix it.

My 64-bit Dell is running Windows 10
