Unfortunately there is an issue with the tools we use to build our ISO (see here) so it will fail to install TROMjaro if you boot in Legacy Bios. I postponed to release an ISO until we fix it but I better release it like that since it is working if you boot in UEFI mode.
UEFI is the newer and more secure form of booting so this should not be a big deal, but we hope the issue will be fixed in the next TROMjaro ISOs.
Other changes:
- The APP Finder works a bit different but more reliably. See here.
- And we removed the AppImageLauncher that was failing to work correctly and replaced it with the more modern Gear Lever.
Else, all good. Enoy 
Grab it from here.
EDIT: The ISO is a lot fatter, over 5.5GB because Manjaro and us added a lot more Nvidia drivers for compatibility.
