LibreOffice 6.3.6 and 6.4.x(x86&x64) very slow startup on Windows Server 2012 R2

Like i’ve said in the title i am experiencing very slow startup of any component, write, math whatever on a server with Win2012R2 (x64).
Very slow means that i do launch the app, then the logo loads and then i have to wait up to 5 minutes for app window to appear.

Does anyone have any suggestions how could i make it work faster, like it’s supposed to?

And how long does a start in LibreOffice Safe Mode last?

almost instant open, like i expect it would open.

Then most probably you user profile is corrupt and you should reset.


according to your “Safe Mode-test”-result, you should reset your LibreOffice user profile.

To reset the user profile perform:

  • Start LibreOffice
  • Start in Safe Mode using Help -> Restart in Safe Mode and confirm the restart using button: Restart
  • Archive your profile expanding Advanced (click on the word Advanced right above Help button) and click Archive User Profile button
  • Select option Reset to factory settings
  • Activate [x] Reset entire user profile
  • Click button Apply Changes and Restart

Hope that helps.
