Why do I get the "Get::noopen" error when trying to load J/Link?

If you receive the Get::noopen error when trying to load J/Link, this suggests that J/Link hasn't been properly installed to the appropriate location.

C:\>math 
Mathematica 4.1 for Microsoft Windows 
Copyright 1988-2000 Wolfram Research, Inc.
 -- Terminal graphics initialized -- 

In[1]:= <<JLink` 

Get::noopen: Cannot open JLink`. 

Out[1]= $Failed 

To correct this problem, it is necessary to place the J/Link folder in the location returned when evaluating this Mathematica command.

ToFileName[{$TopDirectory, "AddOns", "Applications"}]

More detailed instructions regarding the installation of J/Link can be found in the J/Link Help Browser documentation.

As a sidenote, it is recommended that you download the latest version of J/Link if you haven't already done so. It can be obtained through the following URL.
