I tried to run Tecplot and got this error message when Tecplot tried to start up. What does it mean?
This error message means that the environment variable that holds the path down to the Tecplot installation directory is not set correctly. That name of that variable depends on the product you are installing. For our latest products (2008 series) that variable will be called TEC_FOCUS_2008 or TEC_360_2008. For Tecplot 360 it is called TEC360HOME and for Tecplot Focus it is called TECFOCUSHOME. On Windows you can check the environment variables by going to your Control Panel/System/Advanced/Environment Variables. On Linux you will need to set the environment variable in your user profile (perhaps the bash_profile file)
