Can I see how you have your .wxs file setup to call this?

I believe that if it is a deferred CA you will have limited access to the
MSI database (The "CustomActionData" property only pretty much). Are you
checking the return value from the MsiGetProperty? Maybe post your C++ code
so we can take a look at it, but first of all, can you also throw in a
MessageBox() call to see if your CA is getting called (if you haven't
already done that).
