I have installed your software on my computer, thank you, how can I now get it to open office 2010 files?
Thank you

See “Opening an existing document” on page 15 of the Writer 6.0 user manual. You can download this as a PDF, free of charge, from the LibreOffice Documentation page (English documentation | LibreOffice Documentation - Your documentation for LibreOffice). The procedure for other applications is similar.

Welcome to the world of LibrOffice users.

If you did not set it during the installation of LibreOffice, you can specify MS Compatibility. In LibreOffice, go to Tools>Options>Load/Save>Microsoft Office.
If you e.g. open Writer, select File>Open and select e.g. a DOC or DOCX file and click the button Open.
