Hello, I was using office 2010 until today. I am currently a College student so i get the new Microsoft for free so I ended up downloading it to my work computer. Im not 100% positive i Was allowed to do that so now i have a problem. Every time I export a workbook to excel it automatically opens in 2016 and im not able to access 2010. Is there any way to make 2010 default?

If not, I guess i have to go back to using only 2010 and is there a way to delete 2016?

Thanks.
