I can't believe this software. I was finally able to get Kies installed and connected once at work earlier today and then once at home this afternoon using the instructions above. Now, when I try to re-connect to the same phone a 2nd, 3rd, 4th, ...... time, nothing! The "Connecting the Device - please wait" message goes on and on forever! I cannot believe how bad written this program is. This is exactly what happened before where I could once connect but then never again?? I've tried all combinations; 1) plug phone in and then start Kies, 2) start Kies and then plug phone in, 3: try different USB ports, ..... Also, Kies will not auto start when I plug the phone in, even though I have that option set in Kies.
Any other suggestions would be greatly appreciated.
Frustrated!
OK I figured it out...
I was having this problem as well (it would just stay on "Connecting to Device").
Do all the steps others suggested (even removing the program files/Samsung directory after uninstalling Kies).
Again do the steps suggested: regedit.exe, Ctrl-F, find "Kies", delete registry entries, F3 (Find next), repeat.. (don't delete the word "cooKIES").
More steps if you use LauncherPro, etc. - after you switch back to TouchWiz UI, reboot your phone!
The version I reinstalled came from the United Kingdom Samsung website support page for Captivate. The download was way faster than OP's link.
If it's stuck on Connecting to Device, then here is how I got it to work:
1. Quit Kies. Reboot your computer - it will help your installation get all settled and happy.
2. Go to your phone Menu -> Settings -> Applications -> USB Settings -> Ask on Connection
3. Plug your phone in.. choose Samsung Kies... but don't open Kies in Windows yet.
4. It should say "Initializing" on your phone
5. It should eventually say "Connected".. some Autoplay stuff might come up in windows...ignore it.
6. When your phone says Connected, wait a little while,
then open Kies.
7. Ignore the Kies software update
8. It should finally connect with your phone and then tell you about the firmware update (JH7)
9. Go through the steps
10. When your phone reboots, the Galaxy S logo will be there for a while. Don't freak out, just be patient.
So pay attention to the order of #1-6.. let Windows get comfortable with the device you plugged in before opening Kies.
Tell me if this helped or not. I am running Windows 7, 64-bit.
