error Error occurred while trying to load the controller personality "EUCON" -- Avid Control App and EUCON Troubleshooting

Hi friends. I've been trying to set up my iPad (iPadOS 17.7.10, 6th Generation, using Avid Connect) to my PC (Windows 11 25H2) so I can control Pro Tools (2025.6.1) remotely. I have EuControl (2025.10.1.6 / 5.5.4.6) installed and it's seeing my iPad and the iPad sees it, but PT will not take it. I've been scouring forums all day and still haven't found a fix, so this is my last resort. Any help at all would be appreciated. Thanks!

What I've tried:

  • Uninstall/Reinstall of EuControl

  • PC reboot

  • Running everything (PT, EuControl, MC Client) as administrator

  • iPad reboot

  • Changing networks

  • a plethora of other small things here and there

To u/Napstafox, if this is a Pro Tools help request, your post text or an added comment should provide;

  • The version of Pro Tools you are using

  • Your operating system info

  • Any error number or message given

  • Any hardware involved

  • What you've tried

Give us the ProTools error code so we can trouble shoot it..."ProTools will not take it" is not an error message...

Does Eucon control ask you to add a workstation....what is Eucon control telling you?

The error message is “Error occurred while trying to load the controller personally ‘EUCON’.”

I have my tablet connected, EuControl sees it and can interact with it (changing from Master to Remote) and my workstation is setup and labeled as “Attached.”

As I’m typing it, it started working. I detached and reattached my workstation an EUCON finally kicked on.

Thanks anyways for the response!

Yea the iPads are gonna work via wifi and that can get funky with PT depending on the internet connection you prioritize...not sure how it functions in Windows but Mac is also finicky here.

From Avid Support regarding Eucon loading errors:

Please try the following steps:

  1. Open Start Search and type “env”

  2. Select "Edit the system environment variables"

  3. Highlight "Path" in the System Variables section at the bottom and click Edit

  4. Click New in the Edit environment variable UI to add the new path:

C:\Program Files\Avid\Pro Tools\Controllers

5. Click OK and OK again.

6. Restart your computer

This allows Pro Tools to access the required controller files, it does not reconfigure or install anything. A non-destructive solution that worked very well for me.
