Got CCDOps for windows and SGP to connect to the camera and cfw8.
Using the beta 184.108.40.206
Works in Windows XP (of which I had to do an install, hence my delay getting back to you). No, connections to the camera and cfw don't work in Win7 or Win10.
Found the tidbit about the parallel driver only working up to Windows XP. Uggh.
Anyway, I'm plugging away at the software. Consider this connection issue closed (although I have another concern with SGP I'll post in a different section on the forum after I do some research about the problem on my end).
