The program does not open with a message saying "KakaoTalk file has been damaged" even though it has been installed successfully.
Try again. If you continue to experience difficulty, remove and reinstall the program.
If it still doesn't work, run a virus check.
KakaoTalk cannot be executed if the file has been tainted due to a virus or external program.
