After succesfull instalation message from anaconda3 2019.07 installer, I cannot find the scripts file in the installation directory ("C:\Users...\Anaconda3"). 
I found many fixes to installing anaconda and many of those consist of including the scripts file path to the environment variables path. Then I noticed that I could not find this file whatsoever.
I've been uninstalling and installing it but the "scripts" file seems to not be set during install procedure.
Please check whether you have Scripts folder inside anaconda3. 
You can set the path to Scripts folder in the "Path" Environment variable inside control panel(Control Panel\System and Security\System -> Advanced system settings -> Environment Variables) as 
C:\Users.....\anaconda3\Scripts
Hope this helps.
