Openstudio and Energy+ installation error


I am new to ladybug tools and just trying to run a simple honeybee energy simulation following @chris family house tutorial. I got this error message:

  1. Solution exception: No Energy Plus installation was found on this machine.
    Get a compatible version of Energy Plus by downloading and installing
    the version of Open Studio listed in the Ladybug Tools compatibility matrix

I have downloaded both open studio and energy+ separately, together, redownloaded, restated computer, nothing seemed worked. Any help? thanks!!!

download open studio 2.9.1 and just install it in C derive.
