Have just removed all folders except Coverdesigner, Nero and Nero StartSmart.
59 meg - 120 files
Then rebooted and ran Crap Cleaner ( removed 463 reg refs) JV16 2005 ( removed another 67 reg refs) and finally Reg Vac (found 12 more)
Nero Startsmart now only shows Nero, Nero Express, and Cover Design.
Burned some data to a CD -- no problems as yet that I could see.
So Nero has gone on a rapid Atkins diet and looks all the better for it.
