Microsoft Excel keeps crashing

JasonCooper This duplicates a post I just made over at answers.microsoft.com, but it applies to your question.

I had Excel start crashing today while opening .xlsx data logger files. The file would open with the yellow "Enable Editing" bar highlighted, I would click it, click anywhere within the page, then Excel would immediately close. I tried something new - right-clicked on the Excel file and used "Open With". I selected the Chrome browser because it was an option. Chrome immediately prompted me to save the file, so I saved it with "resaved with Chrome" appended to the filename. That solved it.

I just updated my Office files per Tin Zhang's advice - thank you for that. We'll see how it goes.

*** UPDATE *** I still have Excel crashing on half my files, but opening the files with Chrome and resaving the files is working.
