Trying to view a file in Acute3D Viewer, "Failed to load 3D scene, Corrupted Incomplete or Incompatible model, Check the model or get the latest version of the viewer"

Originally viewed on a desktop, at the company we now need to view it on our laptop to show it to a client. The version is v4.4.6.845 . So we don't understand why it won't open it on the laptop but it opens the same file fine on the desktop. Does the file only work for one machine ?
