i purchased microsoft office enterprise 2007 today and tried to download it onto my computer. My computer is fairly old but has xp on it, it currently still has microsoft office 97 on it. I put the main office disc in and it would not read it what so ever. I tried everything but it just would not read it. Then i figured id be able to just put it on my external hard drive from my parents computer and plug it into my computer and it would work...nope. Office works fine on my parents computer while the external hard drive is plugged in but it doesnt without the drive. I plug it into my computer and it doesnt work. An error message comes up that says not enough memory to open word. I researched this quite a bit but had trouble finding anything related to the situation im in. Oh yeah i already registered it with the product key over the phone(which probably really screwed me),but i am hopeful that ill be able to do something to get this to work. Please help me i really need this to work on MY computer for school.
