How do I make Xbox (beta) delete the installation files once a game is installed?

I'm not sure if currently there is a way to make Xbox (Beta) clean up install files. More than likely you'll have to delete the install files yourself (CAUTION) not to delete the actual save file location or the .exe file itself.

Here
is a forum link to known game issues with the XBOX(Beta) application games.

In theory you'd be able to delete any files that would already have installed if you knew where the launcher installs games to, in the Xbox (beta) app, if you click on your profile picture it will show you the default installation location, might be an
idea to try there & see if you can delete the files to try & reinstall them.

In the Xbox Beta app, while clicking on my profile picture - settings - general, it only says (C drive, nothing else. I've been searching for two days after the game file location (just to remove every trace of installation files) for MCC but the files
are hidden for MS Store games.. most of them atleast. Go ahead and tell me where they are.

If you just delete and reinstall the game install, no. Make sure to drill down into the game folder and only delete the large install file, not the save game data.

How are you playing the game: from the disc, installed from the disc, or Games on Demand? If installed/downloaded, delete the file, clear cache, restart, and re-install/re-download. Go ahead and add the map pack(s) into this round too, just to make sure
everything is a fresh install.
