Well, super cool luck last night - I am not sure what did it, but managed to get the ZWO EAF to work under XP on my very old laptop! I installed and uninstalled different drivers, including what you kindly provided, Alan!
In the end, I still have the "latest" ZWO ASCOM driver plus the 3.16 version (a bit old) of their "Cameras" driver. I also installed the older EFW driver that Alan provided...not sure if/why that would help, but at this point, I'm leaving it since it is tiny and the EAF is working!
Lastly - I did get another reply from ZWO (great response time): They said, "Our latest ASCOM driver is not designed to work on XP nor Win 7 32-bit" ... but, that is exactly where I have it all working now, ha! I did let ZWO know of my particular case/results.
Thanks again so much Alan ... and to Adam for starting this thread back then!
