If you are using a network license, your PC needs to know the IP of the server. Open the > System > Advanced System Settings . Click Environment Variables . Under "System Variables," click New . Variable Name: LSFORCEHOST Variable Value: [Enter your Server IP or Hostname] Click OK and restart your PC. 5. Re-generate the License (Standalone Users) If the license file has become corrupt: Go to the ETABS 2016 installation directory. Locate a tool named echoid.exe . Run it as an administrator. Note your Locking Code .
Software that "cleans" your registry can sometimes delete the Sentinel RMS keys required for ETABS to function.
A recent update sometimes resets the virtual ID of your hard drive. If you're still stuck, tell me: Are you using a standalone or network license? Did you recently update Windows or change your system date ? Is your antivirus showing any blocked files?
