I installed zenOn on my PC and when the editor or the runtime is started, a windows installer message appears! Why is this and what can I do about it?
zenOn installs with the editor and the runtime also the merged module VBA from microsoft. As also other applications install these same merged modules (e.g. MS-Office) sometimes a version conflict occurs.

If you do not necessarily need VBA in the runtime or in the editor, you can disable VBA in the file "zenOn.ini" resp. "zenOn6.ini" through the entry [VBA] EIN=0

If you can not disable VBA, please contact your local zenOn support agency to receive a VBA repair setup.
