Screenshot with error message
I'm not able to install the Duden Korrektor 8.0 extention. Error came up after installing LO4.0 with installed LO3.6 and tried to activate the extention at extention manager. Uninstall and reinstall the extention did not help.
See the Germen release notes for a workaround.
