I am opening a document in Excel 2013 and seeing a bar on top "Office has detected a problem with this file. Editing it may harm your computer. Click here for more details."
Then a pop-up "Protected view is preventing you from editing. If you trust the source of this file, click Enable Editing."
I go to file>option>trust center>trust center setting>trusted location, add a path c:\userdata\username\documents and copy the document there. I open the document from that location but still see the above again.
Please advise what else I should try.
