Some toolbars do not appear

I have installed the WISEXT tools but some toolbars don't appear? What should I do?

0. The WISEXT tools are designed for SketchUp 2017 and higher. If you use a version before SketchUp 2017, you will not get any toolbar or menu.

1.   If you have not yet activated the full version of the WISEXT tools, activate them: How do I activate all WISEXT tools?

2.   Verify that the licenses are activated by clicking in the menu Extensions >> Wisext >> Activate or deactivate licenses.

Check that all licenses are set to "yes".

3.   The toolbars can be hidden by selecting Wisext >> Show or hide the Wisext toolbars from the Wisext menu. Click the menu again to make the toolbars visible.
