ViewData.exe will not open on Mac: how to get the scan

ViewData.exe is the launcher supplied with a Carestream CS 3D Imaging export, not the scan itself. On Mac or iPad, keep the accompanying Data folder and use a standard DICOM export instead of trying to run the Windows executable.

What you haveWhat it means
ViewData.exeThe Windows launcher for the recipient viewing workflow. Copying this file alone does not copy the examination.
DataCarestream documents this folder as containing the exported 3D-volume data. Its presence alone does not prove every file is standard DICOM.
A separate DICOM volume exportThe portable image data to request if the original package will not import.

How to open the images

  1. Copy the parent folder. Keep both the Data directory and the rest of the exported package. Do not move only ViewData.exe into iCloud Drive.
  2. Import the folder on iPhone or iPad. In Ossidex, tap +, then Folder. Select the copied folder containing the images, not just the launcher or index. If you received a ZIP, choose Files / ZIP instead. These are the English app labels.
  3. Use the complete DICOM export on Mac. In the browser viewer, choose Open folder. If no images are recognized, use the Carestream export instructions linked below to request a DICOM volume.
  4. Check which reconstruction was exported. Carestream exports can include FDK, MAR or both. Confirm with the sender which series you received rather than assuming every additional series is a duplicate.

What to check if it still does not open

A failed launch on Mac is a platform problem, not evidence of damaged pixels. A folder that contains only the viewer is a missing-data problem. A complete package that contains no readable DICOM needs a new export from the source software.

Ask for the original reconstructed volume, with its resolution and field of view preserved. A reduced export or a screenshot can open successfully and still differ from the intended examination.

Viewer options and format limits

On a Mac, open the browser viewer and choose Open folder for the complete DICOM folder or Open files for a ZIP. Browser format and memory limits differ from the iPhone/iPad app; a successful import does not establish that the examination is complete.

See the matching format or export guide and tested samples and compatibility limits. Ossidex is a viewer and planning aid, not a diagnostic device.

Frequently asked questions

Should I upload ViewData.exe to a viewer?

No. Select the folder with the image data, or request a DICOM ZIP. The executable does not become an image when imported.

Is CS 3D Imaging Lite the same as the scan?

No. It is the recipient viewing software. The image data travels alongside the program.
