Ecatcher
Solution
This error is actually due to older Ecatcher versions that were installed on your PC.
Indeed, to fix the problem you must delete the directory "c:\Program Files (x86)\eCatcher-Talk2M\jre\lib\ext" manually.
In the future Ecatcher setup versions, this directory will be deleted automatically.
