Hi all,
I've been using Node-RED for a while now wrapped as a Windows service with NSSM, but due to Windows updates sometimes deleting the service, I've been attempting to host it on IIS. Everything went more or less ok until it came to the palette manager. It didn't show up until I realised NPM wasn't on the IIS user's path. After that there was a permissions issue with trying write npm-cache under the appdata directory of the admin account that installed node. I fixed that with an environment variable, but now I have a new error from the palette manager install.
Clicking 'View Log', everything looks ok:

The log file is the only indication that something went awry:

The 'undefined' was coming from the log.warn(output); in 'registry\lib\installer.js', so I replaced it with log.warn(err.stack); and got this back:

As far as I can see, there's an intact-looking node-red-dashboard directory and files in node_modules in the userDir, and the permissions look ok to me (owned by the relevant IIS user). So I'm at a bit of a loss as to why it's not finding it. Hope someone can help me chase this down.
I just noticed the log reporting the server is listening on port 8110. I've been serving from port 80 for the time being, and there's nothing on 8110 in the browser. I'm guessing this probably doesn't have anything to do with my issue, but thought I'd point it out now I've seen it, just in case I've done something stupid.
