from Scott Pletcher: > > In my case, Mathematica will not load the
add on packages. I get a 'cant open Statistics'DataManipulation '
(or whatever package I am trying to load). I performed the standard
installation, and all the files are where they should be. Is the a
pointer somewhere that could be off? Thanks > > > > > Hello, > > It

problems that seem very easy to make are 1) to put in an initial backtick:
<<`Calculus`VariationalMethods ^^^^ THIS IS WRONG 2) to leave off
the final backtick: <<Calculus`VariationalMethods ^^^^ THIS IS WRONG
Get and << give the generic error Get::noopen: ''Cannot open ''Calculus`VariationalMethods''''
when either of these errors occur. Needs, on the other hand, gives
a useful error. Finally, you should also check your $Path. Just type
in $Path at the prompt; it should include the addons directory. One
thing that can cause problems here is if you have a v2.2 init.m lying
around; it may be setting the path to the old version's directories.
