My neighbor recently got a new computer and upgraded from Office 2013 to Office 2016. In office 2013, I'm not sure if she had a special setup or something, but when she clicked on .XML files, they'd open up in Excel with no problem. On her new computer, I try to open XMLs and it just asks me how I want to open them. I keep clicking "show more options" and Excel is just not there. I'm thinking I could try to manually select what program I want to use to open it, but I don't know were the Excel executable is under Program Files. Where is it? Are there any other suggestions?
