32-bits Linux installer crashes on run on 64-bits OS

When running the 32-bits Linux installer on a 64-bits version of Ubuntu, it crashes directly. See the attached image for the error. Normally 32-bits installers are backwards-compatible on 64-bits OSes. Because it's not unusual to use 32-bits software on a 64-bits OS, people using the 32-bits version can perceive this as a bug. Maybe some kind of detection can be used in the launcher to check whether the version is compatible with the system and give a more descriptive error when that's not the case.
