the ultimate Droplet couldn't communicate with photoshop thread

[getho]

Is it just me, or does anyone else have this issue? 

this is my final attempt to get to the bottom of why this doesn't work.

I've tried many and varied things, I've had discussions with adobe techs who have not been able to replicate the issue, even with my droplet. I'm posting here because when it fails it seems to fail in a group: I suspect that as lightroom now exports batches of files concurrently that one of the batches fails to work with the droplet.

This feature has never worked reliably. even back to lightroom 2 (or wherever it was introduced). So its now been through 3 computer systems, and its been reliably unreliable on all of them. it is possible that there is a conflict with another app or process that has existed on all my systems. (But I still need to find what)

I've been trying to find log entries that relate. Is there a photoshop or lightroom log somewhere (windows)? I've used the adobe log collection tool, but its no help.

It's just me then?

Probably not totally. But while any integration between apps is likely to have some awkward aspects, in my experience running droplets has always been reasonably reliable. You can also test the droplet by exporting files from Lr, and dropping them onto it in Explorer or Finder. Try that.

There has recently been a problem where the droplet and Photoshop couldn't communicate. I can't recall the exact message, but it is fixed in 2015.8 / 6.8 .

yep there was a problem recently which meant it totally didn't work, and then it was "fixed" which meant it went back to what I was used to: working sporadically. I can run a batch from bridge after export, however I'd rather use the functionality that is supposed to be there.

I don't find it works sporadically - it has always worked reliably until I broke something. That's on PC and Mac, calling the droplet both as a post processing step in Export and as an Edit With external editor.

Large numbers of files can cause a problem on Windows. Lr sends the instruction as a long text string including the path to the droplet and to the files. If that string is too long for Windows, the droplet can fail to launch. You can minimize this risk by keeping the file paths short.

Try dragging the files from Explorer/Finder and dropping them on the droplet. It'll help diagnose where your problem is.
