Answer:
This is because some other software (for example IFC Viewer) has installed an older version of TKernel.dll to the Windows/System32-folder. Tekla Structures uses newer version of that dll.
You should either move that .dll to the same folder where e.g. the IFCViewer .exe is, or uninstall that software. Reinstalling TS doesn’t help in this case, if the .dll file is already there.
