This is German for: "the application is currently running, please close all instances and click "ok" to continue.

Start by reproducing the upgrade with `winget install greenshot.greenshot` followed by `winget upgrade --all`, using the Windows Package Manager environment described in the issue. Review the installer log showing Greenshot is still running and determine the package or upgrade behavior involved; done means upgrading from 1.3.300 to 1.3.301 completes successfully.
