Latest Wwise Launcher v2021.2.1.1450 is not installing certain plugins when their install box is checked.
With 'Authoring' only checked, Windows platform.
REV, Igniter Live, Boom etc. folders and contents are not being created in the ..\Authoring\x64\Release\bin\Plugins directory.
Previous versions of WwiseLauncher had worked fine installing all plugins for Wwise 2019 + 2021 versions.
Note: when installing 2021.1.4.7707, any checked plugin with a version no. that doesn't end .7707 is ignored during install.
(Issue tested and confirmed on pc and macbook pro with no previous Wwise versions installed)
