Adding A2B.dll from A2B for Windows / Baremetal rel19.3.1 gives an error.

On pg. 2-8 of the manual titled EVAL-AD2428WD1BZ_Manual.pdf there is this text:

Setting up Software
Use the following programming sequence to set up and operate the A2B Software.
1. Install the SigmaStudio (Rev. 4.4 or later) and A2B Software for Windows/Baremetal (Rev 19.3.0 or later) soft-
ware from the EVAL-AD2428WD1BZ product page.
2. Copy the A2B.dll and A2Bstack.dll driver files from the installation directory (default) C:\Analog
Devices\ADI_A2B_Software-Rel19.3.0\GUI\x86_x64) into the SigmaStudio installation
( (default) C:\Program Files\Analog Devices\SigmaStudio 4.4). Start SigmaStudio and
verify that the A2B.dll file is selected under Tools→AddInsBrowser. Save before exiting.

--------------------------------------------------------------

Unfortunately, this does not work.SigmaStudio gives an error: "The current selection does not belong to SigmaStudio Assembly. Invalid DLL."

Is there any way to get the A2B features working in SigmaStudio? I have SigmaStudio files given to me by a colleague which I cannot open. (Sigma Studio without the dll just crashes)

I have downloaded the latest SigmaStudio (4.7) and A2B stack for Windows / Baremetal. 19.3.1 (as of today)
