That was the solution, thank you.
First I manually removed the broken plugins, (since I could not locate the CCT uninstall shortcut), then I reinstalled the latest version of Studio Pro.
All the other content and plugins of other vendors remained in place perfectly, as the new install removed the previous install, then reported that it was “cleaning legacy plugin items”, and then completed the full install.
The result was Studio Pro, registered still without additional entry by myself, and all the plugins including some new ones I purchased today were all “GREEN” and ready to function.
Obviously with this new version of Studio Pro one does not want to install the Content Creator Toolkit except if there were any reason to do a roll back to the previous release. So for now I am packing away the Content Creator Toolkit and all previous installers for those specific plugins that are also in stand alone packages.
So other users, just install the latest version, activate the serial number for the Pro features if you need do, and stop there.
Again, thank you for the prompt answer and solution.
