Windows may block plug-ins from being loaded if your browser / extraction program flags them as having been downloaded from the Internet.
The solution is do “unblock” the download (archive file) prior to extracting. It is not sufficient to unblock the AudioManager.exe file. You can unblock a file by right-clicking it in Windows Explorer, selecting “Properties”, and then clicking the “Unblock” button at the bottom or (in Windows 10+) checking the “Unblock” checkbox. (If there is no “unblock” button/checkbox, the file has already been unblocked.)← When starting Audio manager, I receive one of the following error messages for several plug-ins: “Failed to load plug-in ‘…’. Could not load file or assembly ‘…’ or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)” / “Failed to load plug-in ‘…’. Die Datei oder Assembly “…” oder eine Abhängigkeit davon wurde nicht gefunden. Der Vorgang wird nicht unterstützt. (Ausnahme von HRESULT: 0x80131515)”
