to get back on-topic but then slightly off again....
Where are the files normally stashed on a windows machine?
I tried using search on whole c: drive but for some reason - it takes it several hours and then when I come back later - the search window has self-closed!
If you installed it as a global module, then npm prefix -g should give you the root path under which you should find node_modules directory that contains all of your global modules.
