Step-by-step

1. Get the folder and unzip it

  • If you received a ZIP archive, unzip it first.
  • Inside you will usually find a DICOM folder and an embedded viewer.
  • Typical files are RomexisViewer.exe for Windows and RomexisViewer.app for macOS.

2. Open on Windows

  • Open the scan folder.
  • Double-click RomexisViewer.exe.
  • If the program asks for a path, choose the DICOM folder.

3. Open on macOS

  • Open the scan folder.
  • Double-click RomexisViewer.app.
  • If macOS blocks the app, go to System Settings → Privacy & Security → “Open Anyway.”
  • If the program asks for a path, choose the DICOM folder.

4. If there is no embedded viewer

  • For Windows, you can install RadiAnt DICOM Viewer.
  • For macOS, you can install Horos.
  • After installation, open the DICOM folder with the viewer of your choice.
