Dorico Unknown Error with Download

For my application installer on Windows 10, dorico displays this message for every download it requires to install. “Installation failed due to an unknown error. The installer was successfully downloaded to the specified target folder. To launch the installer manually, please double-click the installer file.” All the bars are green but there is only one checkmark on Groove Agent - Instrument. Can anyone point me in the right direction?

Welcome to the forum, Brad. Sorry to hear that you’re having problems with the installation.

If you go to your Downloads folder, then look inside Steinberg, then Windows, then Dorico 5.0.20 Application Installer, you should see an installer: try running it manually.
