Licenser: Wrong Key Format

This applies to all different OS and MXWendler versions

Problem

You attached a dongle and checked the licensed features and in multiple locations 'Wrong Key Format' appears.

Solution

1. Open the config.xml file.

2. Manually remove all entries related to the <licenser>.

Background

Softwarekeys and USB keys can conflict if they are both available. One of them has to be removed.
