Get this message after installing on new precision laptop, used to work fine on my old laptop.  
Initialization circle never finishes.

I uninstalled and reinstalled, and problem remains.

Had similar issue. The user path variable was messed up. Please check and resolve.  
In my case, %PY\_HOME% had quotes which had issues while getting resolved. Removed them.  
Earlier it has quotes around variable %PY\_HOME%.  
To verify I did invoke anaconda power shell and it started clean later on (initially it will throw errors in command prompt). 👍
