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.
