Hi Guys, First of all sorry for being late, but anyhow here is the new working fix :-)
First uninstall all the previous version of samsung kies completely
Download and install the latest samsung kies from officially samsung website
click here I have personally test this trick on version (2.3.0.12035_16_4)and its working
Now this trick is kinda easy and you don't need to download and replace any files
Go Start --> Run ----type regedit
Now go to the following path in regedit
My Computer\HKEY_ CURRENT_USER\Software\Samsung\Kies2.0
Click double click on Region and change it from 'US' to your respective country like for example IN for India. Click OK and then run Samsung Kies ...BAMMM.
you would see Samsung Apps Icon at the Left and side, select your country, login and you are good to go.
here is the pic
Don't forget like and comment if the trick worked..
