W11 - no luck here. I have tried complete uninstalls and reboots in the prescribed order and have cleansed the registry of Eucon items.

I have further deleted folders the installer does not remove for Pro Tools and EuCon in 64 bit and x86 folder paths for Avid, Digidesign along with related Program Data, AppData\Local and AppData\Roaming directories.

I used the EUCON_WorkstationUnifiedInstallWindows_2024_10_0_1 9 to uninstall all applications and preferences.

In my case, I get the same error regardless of whether I attempt to enable Eucon before or after a session is loaded.

I have removed Norton 360 and for testing I have Private Firewall Rules in place for Pro Tools, MC Client and Eucon. Disabled my WiFi so only the NIC is connecting to the router, which worked in prior versions but will compare the documented recommendations.

I have run as admin and non-admin - no impact.

I must have some other conflict and so I will try killing other services to see if I can catch something.
Did you try the fix posted earlier? Remove Steinberg Wavelab from the plugins folder.

We have a fix for this:

This adds directions to tell Pro Tools where to find the missing files. It assumes you have Pro Tools installed on the C: Drive. If not change the drive letter for the path line below.
  • Open Start Search and type “env”
  • Select Environment variables button on the advanced tab (towards the bottom right)
  • Highlight "Path" in the System Variables section at the bottom and click Edit
  • Click New in the Edit environment variable UI to add the new path:
  • C:\Program Files\Avid\Pro Tools\Controllers
  • Click OK and OK again. Restart and you should be able to use Wavelab and EUCON

edit: NOOOT. It worked one time somehow, and after starting PT again just now it DOES NOT work again. Please don't tell me to trouble shoot yet again. It should just work.

previous message:
I can confirm that the S1 is now working again in Windows 10, after removing all preferences and re-installing.


I could not just select an older version to install. There's no revert to old version in Avid Link (which now doesn't load by the way)...

Thank you so much, Eddie! I can confirm that adding C:\Program Files\Avid\Pro Tools\Controllers to my Environment variable path has allowed for the successful W11 communication between Pro Tools 2024.10.1, EuControl 24.10 and Avid Control on my iPhone. i see what you mean about the new version. Remarkable! Really haps right now! "I feel like break dancing."

Okay, I just updated to a new computer and this started happening again. Frustrating to have to do the song and dance again (and Eucon was already working with PT, but lost it now).

Working now. I assume it was wavelab - how was this not fixed in PT 2024.10.2?

You have to download the Wavelab update. Steinberg fixed it, but not sure its out yet.

From the Avid download portal though? I downloaded my installers under a week ago, so probably not fixed yet then.

I did some digging and it will be included in the next PT release. In the meantime, you can try it:

As this is not released yet it's unsupported....but there's very minimal risk as it's been tested here already.
