We were using Ver. 19. After uninstalling we installed ver. 20. The model opens but hangs with message "Tekla structure not working".
Our operating system is Windows 8.
Hi Dhofar Structure,
It seems that you are a Tekla customer on maintenance. Please contact the Tekla Middle-East office (or the Tekla office from which you have purshased your maintenance license). Attach the model causing the crash and a description of your environment (operating system, etc.) so that they can start investigating the problem.
Are you an educator? See options for institution licensing.
