NIS2012 - Gadget no-show on 1 machine

Two substantially identical Vista Ultimate 64 PCs, both upgraded from NIS2011 > NIS2012.

Love the product, improved clarity of controls, fine-tuning/default options rational, slick bug-free install, transfer of prior parameters.

But - gadget pulls a no-show on one of the PCs.  A recurrent problem with several consecutive versions.  Too bad - it's so effective an advert for Symantec - useful, reassuring, renewal-motivating.

 

In NIS2010 I had to uninstall/reinstall to recover the gadget.  Is there a more facile method for 2012?
