Roblox installer crashes with a critical error

Fresh Windows install, downloaded Roblox from the official site and the installer throws a critical installer error halfway through. Ran it as admin, turned off antivirus, still fails. Any fix?

Uninstall it, then delete the Roblox folder in AppData\Local, restart and install again as admin. If your antivirus quarantined something during the first install, that's often the reason, so check that too. Still crashing? Try the Microsoft Store version, it installs differently.
