Installing an Application Package with Mathematica 4.2

The preferred installation location for Mathematica 4.2 is specified by $AddOnsDirectory/Applications. You can find the location of $AddOnsDirectory on your machine by evaluating the command $AddOnsDirectory in a notebook.

Some older application packages will install in the old default directory, $TopDirectory/AddOns/Applications. You can find the location of $TopDirectory on your machine by evaluating the command $TopDirectory in a notebook. Although an application package installed in $TopDirectory/AddOns/Applications will probably function normally, you should move it to $AddOnsDirectory/Applications in order to optimize performance.

To install or move an application package to $AddOnsDirectory

1.	Evaluate the command `$AddOnsDirectory` in a notebook and take note of the directory location given.

2.	Quit Mathematica. If the application is installed on your computer, move the application to $AddOnsDirectory/Applications and go to step 10.

3.	Mount the CD if necessary. You may need to have administrative privileges to mount the CD. A list of typical mount commands for various systems is given at http://support.wolfram.com/mathematica/systems/unix/general/mountingcd.html.

4.	Change directories to /cdrom/Unix/Installers.

# cd /cdrom/Unix/Installers

5.	Change directories to the appropriate directory for your platform.

# cd platform

6.	Run ./AppInstaller.

# ./AppInstaller

7.	Enter $AddOnsDirectory/Applications as the installation directory for the application package. You will see a warning if the installer must create a new directory.

A custom installation allows you to install only parts of an application. A default installation will attempt to install all related files if they are needed. To run the default installation, type d and press Enter.

The installer will begin copying files from the CD to the specified directory. If you are installing the application to a directory that does not contain AddOns/Applications, the AddOns/Applications directory structure is created. Once the installer reaches this point you are not prompted for any further input. Any error messages are logged to SystemFiles/Installation/SystemResources/Manifests/Installation.

Since $AddOnsDirectory/Applications did not contain the AddOns directory, the installer created the AddOns/Applications subdirectory and used this subdirectory as the installation location. You will need to move the application from $AddOnsDirectory/Applications/AddOns/Applications to $AddOnsDirectory/Applications.

First, change directories to $AddOnsDirectory/Applications/AddOns/Applications.

# cd $AddOnsDirectory/Applications/AddOns/Applications

Next, move the application package directory into $AddOnsDirectory/Applications.

# mv application ../../

10.	Each user must rebuild the Help Index by choosing Help > Rebuild Help Index the next time Mathematica is used. Help for the application will then appear in the Help Browser's Add-ons category.
