Halo Reach "DLC Required" (but already played before?)

I've paid for both MCC on Xbox One and then I wanted to download MCC PC the minute it was officially released and so I was asked to pay for it again. I went ahead and just paid for it to avoid headaches. I am pretty sure I read quite all over the web that
owning Xbox MCC also licensed a person to a copy on PC. I assure you I bought them both with the same Microsoft account. I did not buy MCC on Steam, which may have been a whole other issue, I am not sure. I don't spend a lot of time playing MCC on pc however,
as I have it installed on a "gaming HP" laptop which is like a luxury model, high quality Idaho Potato. It was able to play Reach impressively well for a laptop I got as a Hand-me-down. Trying to figure out how to set up these title update files and it's proving
to be a chore.

Hmm... Also make sure the individual games are installed from windows store. Just search for the game "Halo Reach" etc..

I just bought Halo Reach this week and have the same issue. Has anyone figured out a solution yet? Customer Service has been a dead end so far.

im confused about what you mean by licences and packages, pls help

This worked thanks, I didn't think to look at the queue. I had to go back and make sure they were downloaded after I logged into the account mentioned above.
