Thanks Even for all your help.
But I'm still having trouble.
I've made sure all possible Python installs are removed. Deleted all Python
folders, OSGeo4W folders, uninstalled QGIS.
Next I downloaded and installed python-2.7.3.amd64.msi to E:\Python27
Next gdal-19-1600-core.msi. Full install, couldn't set location
Next gdal-19-1600-ecw.msi
Next GDAL-1.9.1.win32-py2.7.msi. This time I got a red cross in the
components panel. I selected 'Install on HD' and put on the bottom
E:\Python27 as the location.
I did a quick test with gdalinfo using the GDAL Command prompt in my Start
menu and that worked. So I assume GDAL is installed correctly.
Next I call gdal_retile.py on this Command prompt and I get this error:
Traceback (most recent call last):
File "C:\Program Files (x86)\GDAL\gdal_retile.py", line 38, in <module>
import gdal
File "E:\Python27\lib\site-packages\gdal.py", line 2, in <module>
from osgeo.gdal import deprecation_warn
File "E:\Python27\lib\site-packages\osgeo\__init__.py", line 21, in
<module>
_gdal = swig_import_helper()
File "E:\Python27\lib\site-packages\osgeo\__init__.py", line 17, in
swig_impor
t_helper
_mod = imp.load_module('_gdal', fp, pathname, description)
ImportError: DLL load failed: %1 is not a valid Win32-application.
So it seems Python is still not correctly installed for GDAL.
I do see C:\Program Files (x86)\GDAL; in my PATH, but not Python. Should I
add it?
I think the problem is with the location of GDAL-1.9.1.win32-py2.7.msi. How
should I install this properly? Leave the default setting and don't install
it?
Change the location the my Python27 folder or to my GDAL folder?
Thanks,
Paul
