I cannot update Windows 10 settings to associate .xls and .xlsx file types with LO Calc and cannot receive these file types as email attachments. I am running LO Ver 5.0.1.2
I have windows 10 on an older computer that has OpenOffice and these file types are associated with Open Office Calc such that I can receive emails with these file type attachments.
LO Calc is the default for other file types like .ods
