So i just intalled libre office and some options seem to be missing form the context menu. At least the option to create a new libre office calc file.
This is a pure problem with your operating system. It has nothing to do with LibreOffice. Judging from the screenshot, you’re using Windows 10.
Maybe this article can help you:
The problem is that another application had hijacked associations from LO.
In Registry, default entries of these keys should be set to these values:
HKEY_CLASSES_ROOT\.odp => LibreOffice.ImpressDocument.1
HKEY_CLASSES_ROOT\.ods => LibreOffice.CalcDocument.1
HKEY_CLASSES_ROOT\.odt => LibreOffice.WriterDocument.1
These changes will allow to find ShellNew keys under respective subkeys there, which is where the data for New menu is taken from.
Associating files using GUI available in Windows is not enough.
