Installation of latest version hangs on register dll's

[MaartenBren]

I purchased the latest version as upgrade today.
After I finished the download I tried to install it but the installation hangs.
It's telling me for hours now that it's installing dBpoweramp Relase 2024.05.30
Registering Dlls. When I hit cancel it deinstalls

Uninstall the old version, reboot system (full shut down and restart), install the new version.
