Hi

Im having an installation package created with VS.NET.
currently it has only the standard user interface dialogs.

I would like to have another dialog during the installation (on the Start section) where the client can type the product license number. Then the installation should call a webservice to verify the validity of the license. in case the license is not valid, the user might have 2 more attempts to submit a valid license. After 3 failures the installation should cancel.

I read sth about the Orca tool, but don't know much how to work with it.

Thanks for any advice...
