When lsynth is installed, the installer creates a registry entry specifying the
path.

Hmm...... I understand your issue. I follow these steps:
1. Use MLCAD to add synthesis specifications.
2. Save pre-synthesis file to disk.
3. Synthesize
4. Examine results.
5. If happy with results, save synthesized file under new post-synthesis
name, and fire up LPub.
6. Otherwise discard synthesis results by creating a New model (File->New)
7. Open pre-synthesis file from disk.
8. Go to step 1.
In LPub open the post-synthesis model file, and generate building instructions.
This solution works best if your entire model is enclosed in an MPD file.
MLCad, LPub and LSynth all support MPD.
I'll try to figure out why LSynth doesn't work well under LPub. The last
problem I found was related to LPub's generation of step-dat files. LPub
creates a separate LDraw file for each step in your model. It applies the
default view angle and any rotations due to ROTSTEP to all the parts in the
step. For some reason, this combined with synthesized parts is broken.
What symptoms are you seeing? Garbled synthesis results, or no synthesis at
all?

I'd guess not.

LPub should ignore this, but if it doesn't let me know.
There are a number of cases where STEP might be ignored:
STEP is first thing in file without any parts added first.
STEP following a previous STEP without any parts added in between.
STEP at the end of file with no parts added.
The trailing STEP you mention should not cause a problem. There is always an
implied step at end of file, so trailing step is redundant. The above is what I
mean for LPub to do.
