Schedule a script: ImportError: No module named arcpy

Question

Hi folks,

I've added a script to a toolbox that I'd like to run every X minutes as a scheduled task. If I try and run my .py file from command line I cannot import arcpy:

[HTML]ImportError: No module named arcpy[/HTML]

Same message if I try and run the script in PyDev for Eclipse, or Idle. I've read this thread but with no joy.

Info
I'm on Windows 7, 64bit
this folder exits: C:\Python26\ArcGIS10.0
I don't know where Desktop10.pth file is?
I have no PYTHONPATH variable

Any pointers appreciated!
James

my script fails If I run it from windows explorer (double clicking it).
I receive the following message running my script in IDLE:     
import arcgisscripting
ImportError: DLL load failed: %1 is not a valid Win32 application.

Check and make sure that the C:\Python26\ArcGIS10.0\Lib\site-packages\Desktop10.pth file contains the following two lines (you can edit it with Notepad):

C:\Program Files\ArcGIS\Desktop10.0\bin
C:\Program Files\ArcGIS\Desktop10.0\arcpy

If not, add them. Hopefully that's the problem.

Thanks guys. I was running C:\Python26\python.exe in my bat file so have now changed this to C:\Python26\ArcGIS10.0\python.exe. Also, in PyDev preferences (Window > preferences > PyDev > Interpreter Python > I've updated interpreters to reflect this so I can now run my scripts in Eclipse. I ran the bat file successfully as a scheduled task all night.

Ruth, I have appended ';C:\Python26\ArcGIS10.0' to my Path environment variable. Is that correct? Should that resolve the following:

my script fails If I run it from windows explorer (double clicking it).
I receive the following message running my script in IDLE:     
import arcgisscripting
ImportError: DLL load failed: %1 is not a valid Win32 application.

Cheers,
