Created attachment 109605 [details] screenshot of where it crashes with the error message Windows 10x64. When running the installer, it crashes at 60% of the first step (Conflicting program check) every time.
This error should already be fixed. Please test it with the pre-release digiKam-5.8.0 from here: https://files.kde.org/digikam/ Maik

Thanks. Can confirm that setup for 5.8 works fine.
Definitively fixed with 6.0.0 installer
