My Computer system is windows 8, today I found after I used Excel 2013 ( I download to my PC), I can't save without wireless. I am confused that I install in my pc hardware, why can't save without wireless, is it unsafe for windows 8? I don't like, want to covert to windows 7, not sure if I can or not
