.NET/Link Installation Instructions

Mathematica 5.x

The NETLink_v121.zip file will uncompress to a NETLink directory. Replace the old NETLink directory in your <mathematica directory>\AddOns directory with this new one. If you installed Mathematica in the default location, it will be at C:\Program Files\Wolfram Research\Mathematica\5.x\AddOns.

Mathematica 4.x

The NETLink_v121.zip file will uncompress to a NETLink directory. Move this NETLink directory into your <mathematica directory>\AddOns\Applications directory. If you installed Mathematica in the default location, this will be c:\Program Files\Wolfram Research\Mathematica\4.x\AddOns\Applications. Launch Mathematica and select Rebuild Help Index from the Help menu. This will cause the .NET/Link User Guide to appear in the AddOns section of the Mathematica Help Browser.

You will also need to install J/Link 3.1 or later, which can be obtained here.

Verifying Your .NET/Link Installation

To verify that .NET/Link is working, try this in your Mathematica session:

In[1]:= <<NETLink`

In[2]:= InstallNET[]

You should get a LinkObject result and no warning messages from In[2]. If you do not have the Microsoft .NET Framework installed on your machine, you will see a message telling you this. You can install the .NET Framework from the Windows Update website.
