Recently I bought the office Professional 2010 product key for home and students online. I downloaded the online link they sent meoffice pro plus 2010 64bit, but my computer doesn't seem to be able to read the file. I've gotten the backup disk, but the installations aren't automatically starting like office 2010 Home And Business cd key they should and none of the applications I have seem to be compatible with reading anything on the disk. Did I buy the wrong version of microsoft office 2010 Home And Student 64 bit key, especially since I don't have microsoft office 2010 64bit key?
