Can you please point me to some good documentation for creating a MSI custom action?
Custom actions provide a generalized way of extending the Windows Installer engine. Due to the fact it's a generalized extension mechanism, it's difficult to provide a universal cookbook for custom actions. I suggest starting with the Windows Installer portion of the Platform SDK which contains details on the base constructs as well as a few custom action recipes. MSDN also has a few examples of how other Microsoft technologies have used custom actions to configure their underlying technologies.
