First, how to do you start Houdini? Don't double-click on a hip file, that won't work because the Houdini environment won't be set up correctly.

What's your houdini.env look like?

You want something like this (PATH is for Windows only):

# htoa config start
PATH = "$PATH;C:/solidangle/htoa/htoa-5.6.0.0_r370661f_houdini-18.0.597/htoa-5.6.0.0_r370661f_houdini-${HOUDINI_VERSION}/scripts/bin"
HOUDINI_PATH = "C:/solidangle/htoa/htoa-5.6.0.0_r370661f_houdini-18.0.597/htoa-5.6.0.0_r370661f_houdini-${HOUDINI_VERSION};&"
# htoa config end

Check Help > About Houdini > Show Details

You want to see the HtoA location at the start of HOUDINI_PATH

If you have other renderers and plugins, I would remove all other plugins from HOUDINI_PATH, get HtoA working, and then put the other stuff back.
