Pine 64 installer OS list blank

[spamsucks]

So I am trying after finding my long lost pine64+ board to install something on it to use. I ran the installer, and click the box to choose an OS, and its blank. There is nothing in the box at all. It shows the sd card, in the middle box. I can get the image, but I dont know how to put the image on the SD card and make it boot. Any assistance would be great. Thanks

Board: 
pine 64 + 2 gig
A64-DB-2G-Rev B

My system
Windows 11 pro
32 GB ram
External SD card reader (the SD card is showing up to the PC)

If you already have the IMG, you can just drag and drop it into the Pine Installer window instead of clicking "Choose an OS". The "Choose" button was initially setup to present a list of downloadable options, much like the RasPi Imager app, but IIRC the sources initially used have been replaced or abandoned and many of the initial IMGs are now outdated.
