Hiya, personally I think it will be fine as long as you dont screw with MSI logic too much. It will all come out in the wash/testing.

I don't think that will be a problem. I have added an extra registry value to the msi itself and that worked for me. So I think the same goes for changes applied with a mst. The msi is merely a wrapper for the legacy setup from Adobe.

Thanks alot for your inputs. every is fine for me too except one.
the problen i'm facing is .. i need to add certain preference files in to user profile. so i included active setup also. when logging in to user i got an error that this process requires administrative privileges..  i think some of the custom action requires administrative privilege..

apart from this every is just fine...
