I bought the whole MCC package but I cannot install Halo 3 ODST, I can install all other games with no problem, I got enough of Space on my HDD too. on the MS store and the XBOX app it says the ODST DLC is installed but when i go into the actual game it’s unchecked in “Change installed games” even tho I mark it and accept the changes, it doesn’t work or gets installed and I’ve tried to reinstall the game 2 times already. Any Bloody idea what I can do to solve this problem?
Exact same issue for me too.
Did you find a solution? Can’t install Halo 3: ODST. Dunno what to do 
Go to the store outside of mcc, navigate to odst and press install. It downloads the license perhaps? Then it becomes available in mcc. This however is not how it should work.
Same problem here, any solution? i install halo 3 odst (12mg) and dont work for me
Same cant install ODST of course the one i wanted to play 343 fix this bug please damit its anoying
