P: Adobe Generator static port inhibiting multitenancy (EADDRINUSE)

[FeedbackCommunityMember]

When greater than 1 instance of Adobe Photoshop launched on a single device (i.e. multiple users on the same shared workstation with photoshop.exe running) Adobe Generator presents an error:

There is a problem with Generator. Please quit Photoshop and try again. If the problem persists, remove any third-party plug-ins or try to reinstalling Photoshop

Further analysis shows that Generator is configured to ONLY use port 8010. So the first user to start photoshop.exe is fine but all subsequent users that try to start photoshop.exe will be presented with the issue.

All modern operating systems are designed in a way that they can be shared and used in a multitenancy environment, it surprises me that software is not being designed that same way. Is there anything that can be done to change this?

Talking with our Generator guys, none of the built in Generator clients use 8010. Are you using any third party panels or plug-ins?

Generator logs may help:

Generator logs are located in the following locations:
Mac:
/Users/[your username]/Library/Logs/Adobe/Adobe Photoshop CC 2015/Generator
Windows:

I can send you an email to get the logs if you're able to find them.

Looks like the Reflow generator Plug-in is the culprit: C:\Program Files\Adobe\Adobe Photoshop CC 2015\Plug-ins\Generator\reflow.generate

Are you using that plug-in? (The Edge Reflow app installs that I think) If not, you can remove it. Should fix it for you.

You're spot on Jeffrey.

Removal of the component "Adobe Edge Reflow Preview" resolved this issue as you suggested.

Thanks for the time you spent on this.

[FeedbackCommunityMember]

We are having the same problem. We are only using 1 custom plugin and removing that plugin does not resolve the error. Everything else is generator-builtin plugins? Here is the generator log from Photoshop for the failure.

Per recommendation by Abobe staff, removing the `preview.generate` plugin from C:\Program Files\Common Files\Adobe\Plug-Ins\CC\Generator resolved this issue for me.
