Edo,
you can try (this is the long way around fix):
NOTE: back up what ever data you want to keep, just incase vista descides to
over write it instead of placing in the c:/windows.old directory.
preform an upgrade from what you have to home premium (which I Know uill
let you install office, ane it will work right), then from home premium,
after you finish your install of office, then upgrade again to your Vista
bussiness.
Yes You will probably need to find a serial # for home premium, if the key
you currently have does not give you a list after entring the key displaying
all 64 bit versions of vista asking which one you want to install. note, you
do not need to activate it ( it probably won't let you activate , but you
will be able to at least get office installed and working proporly then you
just upgrade to your liscenced vision of vista.
I don't know why Ms Has this problem with certin vista releases and don't
have a fix for it, leaving every one who does have this problem to suffer
through it..
