Requiring 2 msi's is not ideal, as that would duplicates 90% of the
distributed, double testing effort, and asks the user to make a correct
decision, and if they make a mistake involve tech support.  All of these
should be avoidable using the wix tool set.

My 32bit prot.exe will run the 64bit prot.exe if the system is 64bit, so
the user does not need to decide.

If Difxis not capable of what prot.exe does, why hasn't anyone suggested
using a CustomAction to launch prot.exe?

I think this is the next route to try, but is something I don't know?

Are there any other options?
