I just upgraded to Parallels Desktop 12. During the installation of toolbox, I lost my internet connection. After regaining the connection, I started Parallels and it seems to work fine as does the virtual machine I'm using. When I go to Toolbox via the preferences menu and click install, the progress bar goes all the way to the end and stalls. Toolbox seems to be in the menubar, but when I click on it, nothing works and when I click the Folder icon it says that Toolbox Tools can't be found. When I then quit Parallels, it is unresponsive and I have to force quit. I restarted my computer and got the same result. Something needs to be cleaned up, but I don't know where to look. A search for Toolbox comes up empty.
