The 3DSurface Viewer requires the installation of an ActiveX™ component onto your computer. This ActiveX component contains the graphics software required by Internet Explorer. It will not affect any other program. Installation is fast and you need only install the component once; downloading and installing the Viewer can take less than thirty seconds over a 56.6K modem connection. Once the installation is complete, you can use Internet Explorer offline to run the Viewer.

The easiest (and fastest) way to install the Viewer is to simply browse to the 'Draw Surfaces!' page. If your computer's security settings are set to their default values, the Viewer will automatically download to your machine. Once a local copy has been cached, a security confirmation will appear verifying the component's Authenticode signature. Click 'Yes', and the component will unpack and register itself. That's all there is to it!

If your computer's security settings have been altered, or if you are unable to correctly install the Viewer for some other reason, follow the 'Full Installation' procedure outlined below.

After installation, please see the 'Using the Viewer' page for more information.

If you originally installed the Viewer using the 'Full Installation' procedure, an entry for it will exist in your computer's 'Add/Remove Programs' listing. Select 'Control Panel' from your Start menu, then double click on the 'Add or Remove Programs' icon. Select 3DSurface Viewer from the list and click the 'Change/Remove' button. Follow the prompts to uninstall the Viewer from your system, then follow the 'Full Installation' procedure below to install the new version.

Alternatively, if your browser security settings permit it, browsing to the Draw Surfaces! page will initiate the download of the new version. If your browser does not permit this, or you encounter some other difficulty, please follow the 'Full Installation' procedure below.
