Office 2011 DVDs purchased from Best Buy fail on older computers

It seems that the Office 2011 DVDs purchased from Best Buy cannot be used on older computers that do not have a “superdrive”. You need a drive that can read double layered DVDs.

One user reported he returned it to the store and they attached a “superdrive” unit via USB port and Office 2011 was able to be installed. I suggest making a disk image in case you need to re-install in the future.
