Well, you 'd have to first unpack the zip file,
rename the resulting directory and zip it again, then "install
from local Zip file"; but I guess that still won't work.

Instead, do install your 'fPortfolio' package into a different
*library* (a Windows folder that you'd typically create first)
than the one the other 'fPortfolio' is in.

Read the help pages    
and  ?library

and then use one of them, probably

  library(fPortfolio, lib = ".. your othter library directory")
