We've seen the same problem, and would also like this decision to be reversed.
Have just downloaded the MSI again, and it now seems to include the 10.4.1.36 compatibility components.
ColchesterRGS: Thanks for letting me (and anyone else following this thread) know! I apologize for the delay in acknowledging - I've been getting this new version deployed to the machines I manage and fighting other fires.
Adobe: Thanks (not!) for the comprehensive communications strategy to ensure we would know about this course change and then reversal.
Seriously, Adobe does do a better job than Apple (I have a boycott going against Apple due to their complete and total refusal to provide any sort of meaningful support for deployment and management of QuickTime/iTunes - neither will be installed on any machine for which I have any degree of responsibility), but as workstation adminstrators we shouldn't have to have the skills of an intelligence analyst to figure out what is going on inside the hive and shouldn't have to be poking around inside MSIs to figure out what's being shipped! It's damn lonely out here - the forward channel from Adobe to us is pretty sparse, and the back channel seems non-existent.
