I've recently upgraded to Windows 10 and can't upload CHDK to my SX280.
When posting requests for help, you will usually get a better response if you describe in detail what you did and what happened. When using STICK, attaching the log file it creates (
sticklog.txt) is particularly helpful.
I've tried using the STICK method but it shows the wrong operating system (Windows NT (unknown) 6.2) and I can't change it to windows 10.
Running STICK on my Windows 10 system shows the OS as Windows 8.1 6.3 . That's normal. I'm not sure why yours says 6.2 but it may not matter.
I've tried Stick jar and Stickx.
The
stickx.cmd file is the one you want to run.
Please post a more detailed description about what you did and saw, and please
attach (do not cut & pasted it into the response) the resulting
sticklog.txt file.
