ETABS, a popular software for structural analysis and design, is widely used by engineers and architects to simulate and analyze the behavior of buildings and other structures under various loads. However, users often encounter issues while using the software, and one of the most common errors is the "ETABS License Not Recognized Error 120." This error can be frustrating, especially when you're in the middle of a critical project. In this article, we'll explore the causes of this error, its symptoms, and provide a step-by-step guide on how to troubleshoot and resolve it.
: Using an outdated license manager with a newer version of ETABS.
📍 : Ensure both ETABS and the Sentinel RMS License Manager are the latest versions provided by CSI.📍 Static IP Addresses : If using a network license, assign a static IP to the server to prevent the LSFORCEHOST path from breaking.📍 Stable Internet : For cloud-based licenses, a flickering connection can trigger Error 120 mid-session.
: For older versions where licenses have expired, some users employ tools like RunAsDate to trick the software into thinking it's running during the valid license period, though this is a workaround rather than a formal fix.
