I have installed LO 7.1 on a Windows 2012 R2 server and it’s working fine but I can’t save documents in the most recent versions of the corresponding Office products. I can only 'save as ’ Word/Excel 1997-2003 (i.e. doc/xls). I have LO 6.3 installed on a Windows 10/64 bit desktop and can ‘save as’ Excel 2007-2019 (i.e. docx/xlsx).
From what I can tell, Windows 2012 R2 will run the later 2019 suite of Office desktop products so I’m not sure why I can’t save LO documents in those formats. Can anyone enlighten me?
