Anaconda navigator not working

[Liya Ann Sunny]

After installing Anaconda, I tried to open the anaconda navigator but it did not work.
When i check in anaconda prompt by running code
>>>anaconda
it got error like this
(base) C:\Users\Acer>anaconda
Traceback (most recent call last):

    from win32com.shell import shellcon, shell
ImportError: DLL load failed while importing shell: %1 is not a valid Win32 application.
