!!!!!!!tring to install office07 enterprise on vista ultimate

hi ppl

field

Im trying to install office 2007 on my vista ultimate, and i get a message
when the installation goes up to about over half,

with the following message

" setup cannot find enterprise.ww\Enterww.cab. Browse to a valid
installation source, and then click ok."


and when i obviously select the source which is the cv/dvd source, the same
message comes up again.



ive read on the internet that some have tried to download the cd to there
hard-drive and it worked ( so maybe how do i do that?) and some have done it
and it still didnt work ( so what would i do)



ive also heard of some mysterious missing file, which is confusing,

so please let me know the best way for me to get this to work, ive been
tryin for ages..........

my pc spec are as follows



intel dual core (total 6GHz)

with over 200Gb hard drive

and 2GB ram

installed vista ultimate genuine
