In case you can't locate the Abvent/BIM Track menu in the Archicad menu bar, you can correct your installation in a few steps:

Launch your Add-On manager in Archicad through the menu Options/Add-On manager.

The Abvent BimTrack Add-On should display in this list. If not, open the section "Edit list of available add-ons".

Click the "Add" button to load the Abvent BimTrack add-on (BIMTrack_A2x.apx).

You will find it in the Archicad 2x / Extensions folder.

Select the add-on and click OK to load it.
