OpenVpn 접속 에러시 해결방법 (All TAP-Win32 adapters on this system are currently in use)

OpenVpn 사용시 접속이 되지 않고 에러 로그에
"All TAP-Win32 adapters on this system are currently in use" 이런 메시지가 있다면
아래와 같은 방법을 사용하면 됩니다.

I'm seeing this error, "All TAP-Win32 adapters on this system are currently in use"

• OpenVPN needs administrative privileges to be able to manipulate a TAP-Win32 adapter, make sure you have administrator access/privileges on this account. Then try OpenVPN again.
• The TAP-Win32 adapter might be disabled. This can be checked by going into the "Network Connections" folder, right-click on TAP-Win32 adapter and select "Enable". Then try OpenVPN again.
  • If there is no TAP-Win32 adapter installed. Run addtap.bat in the OpenVPN directory.

전 위 방법중 OpenVpn 설치폴더의 addtap.bat 란 배치파일을 실행해서 adapter를 업데이트 해주었더니 해결이 되더군요.
