Hi Casper,<br>
<br>
I think you'll need to start from as clean an environment as
possible and add items to path until things break again.<br>
For example, from a command shell (start > run > cmd.exe):<br>
<br>
{{{<br>
:: clear whole PATH<br>
set path=<br>
<br>
:: clear PYTHONPATH, PYTHONHOME<br>
set pythonpath=<br>
set pythonhome=<br>
<br>
:: set basic o4w environment<br>
cd /d c:\osgeo4w<br>
set osgeo4w_root=%cd%<br>
path=%osgeo4w_root%\bin<br>
}}}<br>
<br>
Now run python and import gdal. <br>
<br>
If it works, from the same command shell run each bat in
"osgeo4w\etc\ini" and test the python import again until something
fails.<br>
<br>
If it doesn't work, something is wrong with the current o4w package
ecosystem and we'll try and dig it out.<br>
<br>
If you get through all the ini bat's without error, then the problem
lies somewhere in the host Windows environment. Likely culprits
include things like other python directories or .dll's in PATH,
PYTHONPATH or PYTHONHOME (not necessarily gdal dll's).<br>
<br>
let us know how you make out,<br>
<br>
