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    
     ?.libPaths
and  ?library

and then use one of them, probably

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

Regards,
Martin
