Cortona3D Viewer doesn't render big 3D scenes in any 32–bit supported internet browser

Cortona3D Viewer uses computer memory to render 3D scenes from VRML.

Please close all running applications before launching large VRML files in one of the supported 32-bit internet browsers.

On a 32-bit Operating System, only 2GB of random access memory is available for every application.

In order to use more than 2GB RAM, please install a 64-bit version of Cortona3D Viewer (which can be downloaded here). 64-bit Cortona3D Viewer can only run on a 64-bit Operating System. If the user's Operating System is 64-bit, then large VRML files can be opened in the 64-bit version of Internet Explorer (Start > All Programs > Internet Explorer (64-bit)).
