Custom MSI Setup

Hi Friends,

I have to deploy an Word 2003 application(in .NET) for which I need to create a MSI Setup which on execution will inform the user about the location of the Install and then on clicking the "Next" button, the Installation should complete...Basically, I have to create a simple, easy to use MSI Setup. Now, my problem is that MSI Setup on execution displays various screens and also gives the user the option to change the Installation folder...I have to do away with the various screens and also in my case, the Installation location is fixed...that is user can't change the path...they will simply click the "Next" button and Installation will start. Also I NEED TO CHECK for certain conditions which need to be fulfiled before Installation happens. This means I have to customize the MSI Setup file...How can I do so...I tried the Shared Add-in provided under "Other Pojects| Extensibile Projects" in New Project dialog box, but I still can't customize the screens. The Add-in only allows to change the property values for Screens(like Welcome, Installation folder, etc) but doesn't allow for screen customization...Any help will be appreciated.

TIA.
