Anaconda3 activate.bat is not recognized as an internal or external command

Question

I have downloaded Anaconda3 for windows 64-bit operating system. After the download and install completed, I opened the Anaconda prompt but it give me this nice error:

Answer 1

I think the problem will be solved by clearing all dependencies.
I initially had python installed, 2.7 and 3.6. I just get rid of all of them. The problem is not solved yet.

I discovered that My MySQL server is running. I just closed it but it did not work. I just uninstalled it completely and The problem is solved.
Anaconda needs to listen to , I think 8888 port, which might be used also by MySQL server as well.

I hope this will help.
