On installation attempt I get two error messages, 3503 and 3502

I’m trying to install version 6.2.8 on Windows 10 PC. installation gets interrupted and error message “internal error 3503” then “internal error 3502” appears on the screen. What do I do?

This will be pretty hard to be analyzed without an installation log file (on how to create see at the end of LibreOffice FAQ - General Installation Issues (Windows)) since MSI Installer Error Messages do not contain these numbers.
