When attempting to install the product on macOS Monterey it fails to install with NO real reason just that:
"An error occurred in a program run by this package, which may cause the installation to fail. Please contact the software manufacturer for assistance"

I cam to this error as all my ".rlcontent" files stopped installing with a message "Failed to Load File".

Now I can't use the product or my content which I've paid a reasonable amount of money for ~:(
