In[1]:= $Version (* Just for info *) Out[1]= 5.2 for Microsoft Windows (June 20, 2005) Evaluate the following expression In[2]:= $UserAddOnsDirectory Out[2]= C:\Documents and Settings\Jean-Marc\Application Data\Mathematica Now, with whatever method is available from your operating system, go to the above directory. You should see a directory called "Applications". Within it, create a new directory called "Merger", then copy the file Merger.m into it. In Mathematica again, evaluate the following expressions In[3]:= Needs["Merger`Merger`"] In[4]:= ?Merger --> "This package defines functions used to simulate mergers in differentiated and homogenous product industries. Available functions... <bla bla bla>" At any rates, the following section of the online help is a must read: http://documents.wolfram.com/mathematica/Add-onsLinks/WorkingWithAdd-ons/ HTH, Jean-Marc
