In case this can be helpful to someone, I just ran into the following issues installing Natlink and Dragonfly, and here is how I solved them. I still don't know how I could install the latest Dragonfly, so further insights are always welcome.

Natlink

To get Dragonfly working it sounds like you need to use Python 2.7. Following the instructions seemed to work, HOWEVER as stated in a different post (which was not obvious to find), the base line to install wxPython will not work. You need to specify a specific version of the library for it to install successfully with the old version of Python. So use:

pip install wxpython==4.0.3

This thread has great information and is where I found this.

Dragonfly

This one I haven't solved for the latest, as I am getting a "Visual Studio 9.0" missing error during install. HOWEVER, I did want to let you know that if you are willing to work with Dragonfly 0.6.5, it does still work if you install it (using "dragonfly" instead of "dragonfly2" in the install command).

Cheers, and happy voice recognition

The link to the other thread was broken, so here is the relevant text:

-----------
Make sure you're running the latest version of Python 2.7 which is 2.7.18 -> https://www.python.org/ftp/python/2.7.18/python-2.7.18.msi

When installing the python modules make sure you use the following pip commands from the command prompt in administrator mode:
C:\Python27\Scripts>..\python -m pip install --upgrade pip
C:\Python27\Scripts>pip install wxpython==4.0.3
C:\Python27\Scripts>pip install pywin32
C:\Python27\Scripts>pip install six
C:\Python27\Scripts>pip install future
When I installed on a new computer initially I didn't have the ==4.0.3 when installing wxpython and got the same error as you. It previously used to work without the ==4.0.3. I got the augmented pip instructions from QH, thanks. I have also attached my simplified installation guide for installing natlink from scratch which others might find useful.
