Oh — not a launch problem — you haven’t been able to install it yet. Got it.
The file RoboPaintMac_v2.0.0-Beta.1.dmg is a disk image (not an application) that should open up when you double click it.
After double clicking on that icon, if you can’t see anything, try selecting from the menu Go > Computer
The virtual disk (“Install RoboPaint”) should show up there.
Inside that folder is the RoboPaint App, which you can drag to your Applications folder.
