!!! CreateCTP Error Unable to create specified ActiveX Control

We are getting this error after upgrading to version 8.2.4371.

Everytime Outlook starts, the error "!!! CreateCTP Error Unable to created specified ActiveX Control" is thrown. Dismissing the error message will allow Outlook to continue and load the addin successfully. However, our controls are not shown.

Upon checking in Visual Studio, the Addin designer has an error and would not load. No further exceptions can be seen aside from the message box with the error above that is thrown every time Outlook is launched. There are also no errors in adxloader.log and adxregistrator.log.

Visual Studio Designer Error - The designer did not provide a root component but has not indicated why. Ignoring this error would open the designer but it is missing most of the controls.

Loader version: 8.2.4371.0
Operating System: Microsoft Windows 10 Enterprise Edition (build 10586), 64-bit
Outlook Version: 2016 (16.0.7167.2055)
Visual Studio: 2015 (14.0.24720.00 Update 1)

Downgrading to Add-in Express version 8.1.4350 resolves the issue, confirming that the issue is only isolated to 8.2.4371. Please assist.

Hello Aaron,
