I installed my Parallels Desktop Version 13 on a new Mac Laptop by successfully switching the license from the old Mac to the new Mac. However, when I tried to install Toolbox from the Desktop "Preferences" menu, I got the following message: "Unable to download the Parallels Toolbox installation files. Please check your network connection and try again." I have a network connection that's connected to the Internet. I then downloaded Toolbox, but Parallels only permits downloads of the "latest" version, which does not work with my Parallels License Key. How can I install Parallels Toolbox Version 13?
