Anaconda won't launch

[jonathan l]

I have been using anaconda for a few months and suddenly it stopped working. I uninstalled and reinstalled it and I am having the same problem. Here is the error message I get.

"C:\ProgramData\Anaconda3\lib\site-packages\setuptools\distutils_patch.py:25: UserWarning: Distutils was imported before Setuptools. This usage is discouraged and may exhibit undesirable behaviors or errors. Please use Setuptools' objects directly or at least import Setuptools first.

Any help will be appreciated.
