PSIM License관련 질의
학생 License를 사용하여 PSIM을 사용하고자 합니다. License키는 받았으나 이를 almutil_gui에서 Activation을 들어가 키를 입력해도 License Store: User일 때 Error: Unable to access license store이라는 문구창과 함께 Activate가 되지 않습니다. 또한 이를 관리자권한으로 바꾸어 license store를 user에서 system으로 변경 후 이를 PSIM option에서 license setup을 누르면 누름과 동시에 프로그램이 강제 종료되는 현상이 발생합니다. 이 두가지를 해결하고자 합니다.
