I know what you mean. It drives me nuts when installers hijack 
registered file associations without warning. It has gotten better over 
the years with installers offering the option to select or exclude 
taking over existing extensions. I have added many custom keys over the 
years to select from several apps with special parameters for particular 
extensions. So when these misbehaved installers hijack one of these on 
me, you know I'm not a happy camper.
