@hkosim thanks for your first bugfix PR. Now if the ToolEdition is null, the NPE should be fixed. 👍
However, we do not know for sure if not maybe already installed variable was null.
Then we can still get an NPE here.
Also, please add #1645 to our CHANGELOG within this PR.

@hkosim thanks for your update. Now everything is bullet-proof and perfect. Thanks 👍
Ready for merge.
