Interesting. I did a little more digging and found this: http://dennisbareis.com/makemsi-manual/dllca_c.htm
It suggests that upx.exe is used only to compress dll custom actions residing in the Binary table. I still don't see anything specifically that knows how to decompress the dll prior to calling the custom action so I need to do more research to figure out how this all works. I think it is safe to say though that regular installed files do not get compressed with upx.exe. Edwin G.
