Problem opening LibreOffice

LibreOffice 3.2 worked until yesterday, but now won’t open. I am on Windows 10 version 1511. I can’t find how to open the program in safe mode, or to update Graphics drivers, which are two fixes which have been suggested. I am not a computer nerd, so simple answers please!

Sorry I can’t name a fix for you but just wanted to add that I can’t open LO after I installed the windows 10 Creators Update. I had to roll back the update.
