## My Worker cannot find Blender, what do I do?
When installing and starting the Flamenco Worker you may see a warning in the logs that says
the Worker cannot find Blender.
Example Flamenco Worker <=v3.2 log message...
```
WRN Blender could not be found, Flamenco Manager will have to supply a full path
```
There are two ways to resolve this problem:

There is no concept of a "well known location" in Flamenco. On Windows it finds Blender via the association of the .blend file extension with an executable. Would you know of a concise way to explain this to people who may not even know what a "file association" is?

The $PATH is correct.

So I used the phrase "well known location" to head off custom locations or using NFS/NAS mount and what I meant was platform-dependent-paths: https://docs.blender.org/manual/en/latest/advanced/blender_directory_layout.html#platform-dependent-paths.

I did think about describing in more detail how Flamenco searches for Blender but as you point out some end users may not know or should necessarily need to know this level of detail.

2. Use a [two-way variable named `blender`][blendervar] for each platform (eg: Windows, Linux or MacOS).

This might be a clearer way to phrase this:

I included this phrase in my latest update.

For option (1), Flamenco will attempt to locate Blender by examining the system.
In option (2) the `blender` path for the Worker is sent when a Render Job Task is enqueued.
The Worker will still show a warning on startup and expect the Flamenco Manager to send the Blender
path to use.
