N7 issue after uninstalling N8 [resolved]

My trial version of N8 has expired so I have uninstalled it and removed all references I could find to N8 (including clearing the registry of N8 references).

Now, when I launch N7 (nice to be back) the following message appears:
I am assuming that it has something to do with N8 but I don’t know how to get rid of it.

I’ve never used or even heard of “Caleidoscope” or “Production Grooves”.

After [OK]ing the message N7 launches and runs normally.

Any idea how to eliminate this message?

Caleidoscope and Production Grooves are something to do with Nuendo-8, but uninstalling N8 does not remove them from the system.

Solution was to remove them via Control Panel/Programs & Features.
