cs4 web premium problems

Can someone tell me why when installing web premium, only half the programs such as ,Dreamweaver Iillistrator and Cue are not loading from the disc. So far i have uninstalled every Adobe product with three different uninstall(as recommended by i am guessing India) ran clean script, made a new account and tried to reinstall with no luck. Why should it be this hard to install a plug and play program. at this point i am losing so much time=money , that i would settle to just get back a refund which is apparently not an option. It just amazes me that such a so called advanced software developer can not get things right. and on top of that ....will not back up a product with a warranty.
