Newbie here, how can I download Connexx 8.4 or/and AudioFit 8.4.5 and up? Also what hardware should I get?

[idk idk]

Hello, for the past 3 months or so I searched how can I self fit and program my hearing aids, but I got stuck in a wall, how do I get my hands on the fitting software. I didn't find anything useful on the internet except the DIY School Hearing Aids (v2.2) (respect for the original creator and all who contributed to this), and the second wall was what equipment I need (except the software), but from my understanding since my hearing aid is a bit older and connects with programming adapter 13, so I assume i need the base NOAHlink, but there is another problem, I can't find the base model. Can anyone help me with the download and correct me if I need more hardware then what i said?

Edit: Here's my hearing aid, its a bit old but doing its job

Edit 2: At the bottom of the data sheet it says this "For control ranges and more programming features see Hearing System Simulation
of Connexx 8.4, AudioFit 8.4.5 or higher." Do I need both of them?

• Tip: The Microsoft Edge browser has an excellent .PDF file reader. You can change Windows settings for a PDF file by changing the default application used to open them, which is often done through the Settings app (go to Apps > Default apps > Choose default apps by file type) This allows you to select a different program, such as Microsoft Edge, and choose to "Always" use that application for opening future PDF files.
