Need help with installing game dvd game

Hi, i was trying to install lord of the rings war of the ring. But, i had issues when installing it. at first it went successful, now it says "“errnor30 read only file system”. thats when i was trying to install it through lutris. add game, then install game from the media. when i tried going through the setups. i did accidentally setup cache by mistake.

also, when clicking on setup file in lutris. it says destination folder not writable by the current user.

nevermind, i got the game to reinstall by using a program called: “flatseals”.
