LibreOffice does not open, except in safe mode. Why?

What is Restart in Normal mode? How to install SketchEI-1.62.jar(chemistry extension) in libre-office? What is the difference among open office, WPS Office and Libre Office? Is it useful to have both windows 64 bits and 32 bits versions of Libre Office on my HP laptop?

Safe Mode is basically a test to see if the LibreOffice user profile is intact or broken.

If you detect a problem in LibreOffice, you can use Safe Mode. If the problem does not exist anymore, you should reset your user profile.

Title edited.

If it works fine in safe mode and not with the standard launch, then reset your LibreOffice user profile (rename it).
