问题
I'm new to django and using the anaconda cloud environment. Its been working well for 3 months plus but as of 7-24-2018 it is just stop to launch the navigator or open through cmd. I can't manage environments or install packages. Using the anaconda prompt also gives me the same error upon launching. It started when I wanted to install django-Oscar, but not having its dependencies I was forced to install the packages manually which in turn needed cytoolz that needs Microsoft Visual C++ build tools which I got to install as well but the error persists. Please help me!
Copy/Paste of CMD Traceback:

I've just found out that I cant even use any conda commands except the : >conda --version< command only. Please help me resolve this issue without uninstalling then reinstalling anaconda completely

Sorry to waste your time, I solved it by reinstalling anaconda completely and every project started working again....thanks to those who read it, the effort is appreciated.
