Wow, all seems to be there and working.
Many, many thanks for all the good advice and for spending the time.
One query, how does the slim install differ from the regular install?
I must be doing something wrong but I do use the standard installer, as you have well illustrated, but I continue to get the "portable" interface. Can you kindly suggest where else to look.
I agree this is taking way too long but I don't know what else to do.

I downloaded the free version from https://www.ccleaner.com/ccleaner/builds and it picked up my license for the pro version. I use to use ccleaner64 but that seems to have vanished.
