I am unable to run OpenTower Designer as an user; it does not start and no errors are reported. I can run it as an administrator.
Please check if your machine has the following Microsoft Redistributables installed:
If application stops after splash screen then please check if the custom database is installed properly and as well as the correct connection client.
If the 3D model is not showing then please check if 2005 and 2008 Microsoft redistributables installed in the desktop or laptop
If the analysis is not performing then please check if 2013 Microsoft redistributable installed in the desktop or laptop
