I'm making a general comment on not just kies, but makers suites to connect your mobile ... be it , samsung, Nokia, LG or whatever to your PC.
The only one that really worked was the Nokia PC suite.
The LG was the next one I tried. Reading through the forums, getting new drivers from Malasia and in the end giving up using the suite and using direct data connection
The samsung galaxy s plus, my present mobile, has a PC suite called KIES, which has exactly the same problems as the LG version. Impossible to connect to the PC.
Having said that , fortunately the Galaxy does have an SD card and you can insert this directly ( with adaptor) into the PC as another drive.
In my case I only need to back, music, video amd contacts which are easily read on the PC from the microSD card.
There is a plethora of "tricks" to connect mobile to PC. Some people say, this is the way to go. Others say, ... doesn't work for me. etc etc
Not worth the effort trying to make KIES work. Work meaning, bidirectional data flow of your mobile data for storage on the PC or for updating the mobile.
