After I installed the update for 4.0.7 (I had 4.0.6) and also applying the Dutch patch 4.0.7 after it, I get the following error when starting the app.
Run-time error '372':
Failed to load control 'vbalExplorerBarCtl' from vbalExpBar6.ocx. Your version of vbalExpBar6.ocx may be outdated. Make sure you are using the version of the control that was provided with your application.
The app. doesn't start.
I am about to try the full download now.
edit: the full install did work
