Hi,
I attempted to enable product downgrading by setting
IFPkgFlagAllowBackRev=true but this does not work on 10.4.11.
The only one way I could get it to work is by removing /Library/Receipts/MyApp.pkg/Contents/Info.plist file in the InstallationCheck script. This is quite a hack. Without it the installer warns that a newer version is installed on the target drive and later refuses to install saying 'You cannot continue. There is nothing to install.'

Am I am missing something here?

I've seen something similar with a package being installed through the installer command line tool. The installation fails silently even when the IFPkgFlagAllowBackRev flag is set.
