anaconda installation error and jupyter notebook

Question

When I install Anaconda, it does not start and gives an error.

And when I try to use Anaconda prompt to boot jupyter notebook, it gives this error and nothing opens at all.

this is the error:

Please do the following:

pip uninstall pyzmq

pip install pyzmq

The thing with conda is that it may have some conflicts. Using this simple method with pip command, should help you to remove those conflicts
