Hi Tina,
Usually an installation of Python will add its directory to the environment variable %PYTHONPATH%. Open a command window:
<WinKey>+R
cmd /k <enter>
>set | find "PATH"
you should see a listing for PYTHONPATH there. Make sure this points to your actual installed location for Python (usually c:\python24). If not, try:
>set pythonpath=%PYTHONPATH%;c:\actual_python_location\
Then reboot. Windows can't do anything without a reboot.
py.dll is the dll for the Thomas Grill's external and you need to have its full exact path specified in Pd's Path... options. It fails to load if it can't find Python24.dll, but pointing Pd directly to Python24 doesn't help...
Hope that helps you!
David
this lists your environment variables. Do you see a line
