The main reason self registration fails is that some prerequisite
product is not yet installed.
See the "SelfRegister" command for more details.
Its possible that your MSI is self registering more than one
object and it may need to occur in a particular order.
You could use "Dependency Walker" to check
for this as it shows dependent DLLs etc.
