Further to my post last week regarding Adobe CS3 Deployment.. and we found that it is not really possible with an MSI.
Here is a solutions which i have just followed and works very well and did the job just how i wanted it to.
Sorry if this has been posted before, but as no one has mentioned it i assume it hasn't
I will add this to the Wiki aswell.
Hope it helps.
