Thanks, Ted. I'm having trouble locating the .pth file. Do you know where it usually lives or whether it is simply a matter of creating one? Thanks again.
I would create a file, a text file, save it as a .pth file with the following paths (On Win7) and place it in the Lib\site-packages folder:
C:\Program Files (x86)\ArcGIS\Desktop10.0\bin
C:\Program Files (x86)\ArcGIS\Desktop10.0\arcpy
C:\Program Files (x86)\ArcGIS\Desktop10.0\ArcToolbox\Scripts
Make sure you install python 2.6.5, and numpy 1.0.3.
Make sure you have arcpy in the ArcGIS path like: C:\Program Files (x86)\ArcGIS\Desktop10.0\arcpy. If arcpy is here, then the .pth file should work. if arcpy is not located here, then I would try the add features for the install to try and trigger the arcpy ArcGIS scripts to load.
