OK I know "Nikon" and "freebie" are words you do not normally is in a positive comtext in the same sentence, but here is an exception to that rule. You can downlead this application from:
http://nikonusa.com/software/viewnx/...NX100NSAEN.exe
Of course it does not give you the functionality of Capture NX, but if you shoot in RAW it does give you some useful functions to organise and peform basic functions to your photos (rename, convert format, resize etc).
It is obviously aimed at Nikon users, bit will work with any graphic files so as it is free, why not give it a go. (Of course it does contain a hidden macro to destroy anything from a Canon...

)
