Hi Bruce,
To promote the portability of geoprocessing models that include MGET tools,
we moved the primary location of the toolbox to C:\Program
Files\GeoEco\ArcGISToolbox several months ago. I apologize for not making
this more obvious. We need to create a FAQ on the MGET home page that
includes this issue.
The reason for this change is that we discovered that ArcGIS geoprocessing
models internally refer to tools using a path to the toolbox, rather than the
toolbox name or alias. This caused problems when someone wanted to give a
model to their friend, but their friend had a different version of Python or
had Python installed on a different directory. For example, if you had Python
2.4 and built a model that included MGET tools, the model internally
contained a reference to
C:\Python24\Lib\site-packages\GeoEco\ArcGISToolbox\Marine Geospatial Ecology
Tools.tbx. If you copied this model onto a machine that had Python 2.5, the
MGET toolbox would be in C:\Python25. When you opened the model, ArcGIS would
complain that it couldn't find the MGET tools, because it would be looking in
C:\Python24.
To solve this problem, we had to put the toolbox in a location that was
likely to be the same on all machines. We considered creating our own
subdirectory from the root of C:, such as C:\GeoEco, but decided that
C:\Program Files was common enough that we could put it in there. Although it
is technically possible for users to change their official Windows Program
Files directory to a different location, it causes so many problems that even
Microsoft was afraid to change C:\Program Files to a different name for
Windows Vista. (Unlike the C:\Documents and Settings directory, which
Microsoft was not afraid to change to C:\Users on Vista). Given this
evidence, we decided that C:\Program Files\GeoEco was a good choice.
All of that said, there should still be a copy of the toolbox in
C:\Python24\Lib\site-packages\GeoEco\ArcGISToolbox for backwards
compatibility. Do you not see one there? If there isn't one there, nor in
C:\Program Files\GeoEco, then there must have been a problem with the
installation. If so, let me know and we'll dig deeper into the problem.
Best,
Jason

Hello I´ve just downloaded the latest version of EcoGeo but I don´t see the
toolbox listed in the path C:\Python24\Lib\site-packages (as you instructed
another user in a previous post). Could this be the result of incompatibility
with newer versions of Python?
Best,
Bruce
