Windows Client not Accepting Outlook call request

[mikopia]

We have 3CX Standard. I have been using Outlook 2013 with the 3CX Windows Client fine for over a year. The 3CX Windows client updated itself today to version 16.3.0.179.

The Windows client is in CTI mode and that is working, since if I click on an extension, or dial a number from the application, it does that on my phone.

Now, when I right click on a contact in Outlook, it gives me the options to dial, and I can click on them. However, nothing happens in the Windows client. Looking at the log file, I see this:

[28.10.2020 19:29:45.305][28] Pro only MicrosoftOutlookPlugin, Version=15.0.945.640, Culture=neutral, PublicKeyToken=bac47dd19dc4098a
[28.10.2020 19:29:45.305][28] Error occurred when trying to initiate call in plugin handler

   at _3CXWin8Phone.CallHandler.Prologue(Assembly callingAssembly)
   at _3CXWin8Phone.CallHandler.MakeCallAction(Assembly callingAssembly, Action action)

I have tried completely removing and reinstalling the Windows client as well as the 3CX Plugins from the 3CX site.

If my memory is correct, this integration requires a 3CX Pro or Enterprise..

Since when? The Outlook integration page says it works on Standard. We just have to install it manually. And it is working for other extensions.

One of my clients reported the same issue.
It seems to be related with last update.
Previously, the plugin was working on a free standard license for years.

Is there any way to go to a previous update? Doesn't it check for a new update when it is first opened anyway?

Any official comment from 3CX?

I didn't hear anything. Ended up upgrading license to professional.
