Can't Download Forza Horizon 2

For example I have downloaded Forza Horizon 5 but can't play it on the cloud. But can play Forza 4 on cloud

Hi SquallLion1

Unfortunately Forza Horizon 2 - Storm Island has reached "end of life" status and was removed from Xbox store on September 30th 2018

Here is an extract form the Forza Week in Review post on https://www.forzamotorsport.net

"Forza Horizon 2

A heads up for the Forza community: Forza Horizon 2 will reach “end of life” status on September 30. That means that the game and its associated DLC will no longer be available for purchase. After September 30, players who own Forza Horizon 2 will still
able to download and play the game and its associated content as normal. However, Forza Horizon 2 and its DLC will no longer be for sale. Forza Horizon 2 is currently available as part of August Games With Gold so, if you haven’t played it already, now is
a great time to grab it."

For the record, the issue started for me after having downloaded Forza Horizon 2.

First thing you should do is delete the game. Then delete the your system cache. Once you have done that, then download 1 or 2 demos that is the same size as Forza Horizon. Then redownload Forza Horizon. Play Forza Horizon. If the problem has gone,
you can delete the demos.

That's what I did. I went to my library and Forza Horizon 4 was there but I can't download it.
