how to open a microsoft DOCX file emailed to me as an attachment.

every time I try to open error:The requested operation requires elevation . Don’t know what that means. my LibreOffice program is already check in properties “to run as administrator”. Appreciate your help, Gary

Upload to a convert portal like zamzar.com and let them convert into odt format. If they fail the docx file possibly is corrupt.

If your attached docx file is very important so ask your query in Index page • Apache OpenOffice Community Forum - they sometimes “rip” corrupt Winword files for questioners…

Link of last query referred to corrupt Winword file: [Solved] This is not a WinWord6 file, General input/output (View topic) • Apache OpenOffice Community Forum

Your question apparently is about your operating system rather than about LibreOffice. Ask in a relevant forum.
