3CX client is running in background, but no visible window

[bit101]

Hi togehter,

we have the same problem like in this thread:
https://www.3cx.com/community/threads/3cx-client-for-windows-wont-start.79484/#post-369822

We can see that the 3CX Client is running in the background but we have no icon tray and no visible window.
Reinstallation, programm kill in Taskmanager and reopen does`nt get success. Very strange is that the
at 01:30PM afternoon it works suddenly.

I have never seen this before.

We use 3CX Windows Client 16.3.0.220 on Windows 10 (20H2)
We also use the Sennheiser Epos plugin. The Epos Config Tool is also not visible.

regards,
beon

This has nothing to do with the plugin, but rather with the fact that the client remembers it's last location on the screen.
There are some cases when Windows might mess up the resolution for split second on boot, the moment the 3CX Client is launching, causing it to spawn off-screen.

There is a nice trick to get it back, if you see it in the Task bar:

1. Hold Shift and right-click on the Task bar icon of the 3CX Client
2. Left-click "Move"
3. Press any of the Arrow Keys on the keyboard
4. The 3CX Client Windows should snap to your cursor and you can drop it anywhere you want
5. Go to the Menu --> Exit Client

Now when it re-launches it should be fine.

Hi Nick,

the problem is that we do not have the 3CX icon in the task bar. We can only see that the client is running as process in the taskmanager. Thats all. No window or icon at all.

Ok, last idea I have then is to:

1. Exit/kill the process completely
2. With a Text Editor open %appdata%\3CXPhone for Windows\3CXPhone.xml
3. Find lines starting with "<MainWindowLeft>" and "<MainWindowTop>"
4. Set values for both to 0
5. Save File
6. Re-launch

Sennheiser Epos plugin

Is it up to date? Is 3CX being run as a standard user? We had issues like that in 2019-2020 with Sennheiser. IIRC they had a bug where it (Sennheiser) was trying to mess with certificates on open and couldn't as a standard user, so it was hanging. We spent quite a lot of time on it with them, and currently don't have the issue.
