Usually, the (.bat) batch file that is written out by the Python script has PATH and RAYPATH variables defined for that specific session. It looks something like this:

```
SET RAYPATH=.;C:\Radiance\lib
PATH=C:\Radiance\bin;$PATH
c:

```

I am not sure if this is applicable if you are using one of the new variants of Honeybee. This query would best addressed on the Ladybug forum: [https://discourse.ladybug.tools/](https://discourse.ladybug.tools/)
