# Eric Weisstein's MathWorld Packages in Mathematica 9.0 will not initialize

GROUPS:
 Hello,Let me start by saying I am completely new to Mathematica, and I just installed version 9 about an hour ago.  So apologies in advance if I'm doing something silly here!I am trying to run a Mathematica notebook found here: http://mathworld.wolfram.com/notebooks/PointLattices/Polyomino.nbApparently I need the Mathworld packages available in the zip file here, particularly polyomino.mhttp://library.wolfram.com/infocenter/MathSource/4775I have unzipped the add ons and put them in a MathWorld folder as instructed.  I put this in a few different places that should be accessible to Mathematica.However, when I try to run the notebook, I consistently get: (Debug) In[1120]:= <>(Debug) Out[1120]= $FailedI don't know if Mathematica can't find the file, or if there is a problem with the code. I think they were created for Mathematica 6.0, so maybe they are no longer compatible.Would any kind soul take a look at this and see if they can get this Polyomino.nb to work on Mathematica 9.0? Maybe I am not doing something very basic correctly.Thank you in advanceRob Answer 10 months ago 1 Reply  Bruce Miller 2 Votes Get::noopen says that the file could not be opened, not that there was a problem with the code inside. Is the MathWorld folder in one of the directories listed by evaluating$Path? In[7]:= \$PathOut[7]= { "C:\\ProgramData\\Mathematica\\Kernel",  "C:\\ProgramData\\Mathematica\\Autoload",  "C:\\ProgramData\\Mathematica\\Applications", ".", ... Another method of specifying the package is to provide the full path to it.  - Type Get[]- place the cursor between the square brackets, - go to Insert menu, File Path, - in the directory dialog box that opens, trace down to the .m file and Open it (that puts the path into the Get),- evaluate the Get that now has the file path.
