ipcluster3.exe failed to create process

Question

I am trying to run ipcluster3.exe on an Anaconda python 3.3 installation on Windows 7 64-bit.

However, when I run it I get an error:

C:\Anaconda\envs\py33\Scripts>ipcluster3.exe
failed to create process.

C:\Anaconda\envs\py33\Scripts>ipcluster3.exe start -n 4
failed to create process.

The error doesn't really give me enough to start debugging.

Answer 1

It looks like my copy of Anacondas came with a Beta version of IPython.

I updated it using Conda.

conda update -n py33 ipython
