THX Spatial Audio Redownload?

hello, i recently got a razer keyboard and mouse, so as natural, when  brought with the option i installed razer sypnase and razer cortex, along with some modules etc such as THX Spatial Audio, but when i clicked on it nothing happened, so i tried to fix it and opted to uninstall it to then re download it as i do with other applications. But unfortunately, i can not for the life of me find a way to reinstall it, so im quite perplexed,  is it not possible  to reinstall it?

Thank you to whoever responds.
