Registry and module error installing Natlink (Python 38 on Windows 10)

Recently, I have had to reinstall the operating system on my machine. In the process I upgraded Dragon NaturallySpeaking (DNS) from v13 to v15 and in reconfiguring my voice recognition environment (DNS + Natlink + Dragonfly) the following Natlink message now appears on DNS start:

Failed to find Natlink key in Windows registry.  Failed to extract value from Natlink key.  An exception occurred loading 'natlinkmain' module  Error message:  No module named 'natlinkmain'  

--

My DNS version: 15.61.200.010

My OS specifications:

• Edition: Windows 10 Pro
• Version: 20H2
• Installed on: 3/‎12/‎2021
• OS build: 19042.867
• Experience Windows Feature Experience Pack: 120.2212.551.0

To troubleshoot I have:

1. Reinstalled Python and Natlink several times to ensure that I'm installing correctly (per the NatLink installation instructions):

Python 3.8.8 (32-bit), all users, at C:\Python38-32

I also cleared my system of all Python and Natlink remnants and restarted the operating system with each reinstall.

Everything I have attempted has been with OS administrative privileges.

2. Added additional system path variables in the following order:

    C:\Python38-32\Lib\site-packages\natlinkcore\      C:\Python38-32\Lib\site-packages\      C:\Python38-32\Scripts\      C:\Python38-32\  

3. Added the following registry entry:

This last effort advanced initialization past the first message above to this new DNS startup Natlink message:

An exception occurred loading 'natlinkmain' module  Error message:  no module named 'natlinkmain'  

4. Attempted to import natlinkmain:

Additional information...

I did notice that using C:\Python38-32\Scripts\start_natlinkconfig.exe to configure Natlink produces the following error message only on the first initialization attempt:

The executable would also produce two GUI configuration windows, but run successfully despite the error message and the two windows.

The corresponding message in .natlink\configurenatlink_error.txt:

Traceback (most recent call last):    File "c:\python38-32\lib\site-packages\natlinkcore\ConfigureNatlink\configurenatlink.pyw", line 1355, in <module>      app = MyApp(True)    File "C:\python38-32\lib\site-packages\wx\core.py", line 2137, in __init__      self._BootstrapApp()  SystemExit: OnInit returned false, exiting...  

The settings in .natlink\natlinkstatus.ini:

[usersettings]    NatlinkPydOrigin = C:\Python38-32\Lib\site-packages\natlinkcore\PYD\natlink_3.8_Ver15.pyd

At this point I am out of ideas and am wondering if anyone has come across this error message before and resolved, or have any ideas on how I might resolve it? I need Natlink to successfully launch in order to run Dragonfly word macros.
