Run the setup file. The interface may look dated (resembling Windows 98 software), but this is normal. Follow the on-screen prompts. It is recommended to install the software in your C: drive directly (e.g., C:\Smartcarve ) rather than in Program Files to avoid permission issues.
Always perform a "frame" test first. Smartcarve 4.3 has a "Move to original" button that outlines the job perimeter without firing the laser.
