Periodically, we will update our software to add new features and improve the interface. To get the latest version of Steelray Project Viewer, from the Help (?) menu select Check for Updates... This will open the Steelray Software Check for Updates page in a web browser window. If you are not running the latest version, this page will provide links to the latest and greatest version. Select the link appropriate for your operating system and download the file. Locate and run the downloaded file to install the software. This will not modify your existing license key.
If a quick search doesn't answer your question immediately, contact Sales or contact Tech Support.
