Alternative Tools: Maybe keep in mind that commercial tools have features that are easier to use to get your product out there quickly. WiX is great though.

Prerequisites: I would suggest you add a LaunchCondition to the package to abort installation if the .NET framework is not there. You can bundle the .NET framework with your application, but I really do not recommend that: Outdated prerequisites in packages.

LaunchCondition: The concept of LaunchConditions checks for a certain condition to be true before installation is allowed to continue:

• Check if prerequisites are installed before installing a windows installer package (please check this link at the very least - if you don't check other links)
• An earlier answer on LaunchConditions.

Quick, inline sample:
