We tag our master merges with something like snapshots/2020-12-31. Hence, because of our git describe mechanism these strings will be part of the installer filenames. Obviously there's a conflict with the slashes so we should somehow escape/replace them in the filename.

Currently, the installer filename on Windows is something like 2020-09-25-123-gabcdefab-windows-x86_64 so it produces at least something by accident but even the MITK prefix is missing.
