So I downloaded the 7z file and extracted the files using zip extractor app, but I cannot seem to figure out what file actually installs the software. I have tried the most of the "setup" files and "exe" files but I keep getting errors. For the SPD-860.exe file at the end (which I think is the correct file) my computer is saying where is the "main" and wont go any further with the set up. Any ideas or help is appreciated. This remote learning stuff is making everything twice as hard!
