It is very difficult to determine precisely what the issue is
when you have posted no code to show what you have tried or what
you are trying to do. I can offer the following observations.

First, it is not necessary to download this package to use it.
It should be installed in the LegacyPackage directory. If you
look at the list of directories stored in $Path, one of them
should match the directory returned by




should load the package. Note *load* the package. This is not a
function call. To use the functions defined by this package you
will need to use the specific function with the proper syntax.

You will see a warning about possible conflicts between the
functions defined by this package and newer functions in version
6 of Mathematica. For this package, this warning can be ignored.

You did not indicate why you are using one of these functions.
One possibility is that these functions return all of the roots
that occur in a given interval. If this is the reason you are
using this package, I suggest you consider downloading Ted
Ersek's RootSearch package. That package is compatible with
version 6 and offers a more convenient way to get all of the
roots in a given interval.
