After u un-install it , go into your registry and delete the ols Samsung PC Studio files. That is the reason this is happening due to the fact your computer recognizes the program has been installed before. Go to HKEYCURRENTUSER, go to Software and find Samsung ,click on it then find Samsung PC Studio and delete all remnants of left behind (right click and select delete).. Next go to HKEY_USERS u will see numbers such as S-1-5-18 then u wil see one with more numbers such as S-1-5-21-1017465001-2789979257-3684444893-1000 (your #'s will not be exactly the same) and when u see the larger number click on it and go down to Software , click on it and then find Samsung, click on it then find Samsung PC Studio and right click on it and delete it. Restart comp & re-install.
