Could not start python kernel


I have to rollout Knime in our company. I have 3 Windows 7 64 bit Test Clients. On 1st PC it works fine with Python, on 2nd I had an error "Could not start python kernel", but after opening IE it works, the 3rd one always "Could not start python kernel", anything I'm trying. Preferences Python in all 3 cases successfull to apply.

Need help please!

Thx, Gill

In which file does Knime save preferences ?

Thx, Gill

Hi Gill,

the preferences can be found in '<KNIME-Workspace>/.metadata/.plugins/org.eclipse.core.runtime/.settings/'.

Concerning the 'Could not start python kernel' problem: Can you provide the knime.log?
