[MiKTeX] Update form local disk

[Francisco A. S. G. <fg...@us...>]

Im am having problems downloading the LM package using the miktek update 
wizard (it hangs somewhere), but I can download it directly from ctan (I 
downloaded teh miktex\lm.cab). How can I use miktex update wizard to use 
this CAB to update my system? I tried to update from local disk, but it 
found nothing to update.
