I'm getting hard drive images from someone that I am tweaking with my own software. But, The image has Office 2007. I've noticed that when I try and save an Excel document, it defaults to *.xls, not the newer *.xlsx extension that I want. Now, I've searched online and everywhere I look, it says
- Click on the office icon.
- Select Excel Options button.
- Select Save from the left pane.
- Select the extension under the "Save files in this format:" drop down.
- Select OK.
I do all this and doing a save will default to *.xlsx extension. However, when I close and reopen excel, it's back to square one--defaulting to *.xls. Any ideas?
