MatLab설치하는 과정에서 위 그림과 같은 에러가 발생하였습니다.
오류메세지는 다음과 같습니다.
The hostid in your license file must be for this computer. Obtain a new license file generated for this computer's hostid from the MathWorks License Center or License Manager.
현재 네트워크 라이선스 매니저의 경우는 사내 서버PC(Linux만 설치되어있는)의 host id 값으로 설정했고, MatLab setup의 경우는 로컬PC(Windows)에서 사용합니다.
혹시 위에서 두가지 프로그램이 다른 PC에 설치가 되어있어서 위와 같은 에러가 발생한건가요?
네트워크 라이선스 매니저와 MatLab의 경우 같은 PC에 같은 host id여야 설치가 가능한걸까요?
빠른 답변 부탁드립니다.
감사합니다.

An error as shown above occurred during the installation of MatLab. Currently, in the case of the network license manager, it is set to the host id value of the in-house server PC (where only Linux is installed), and in the case of MatLab setup, it is used on the local PC (Windows). Did the above error occur because the two programs above were installed on different PCs? In the case of Network License Manager and MatLab, do they have to be the same host id on the same PC to be installed? Please reply quickly. thank you

Hi @Dong Joon Han,
You may be receiving this error message for 2 reasons:
  • You have selected a license file that was generated for a different physical/MAC address than the one your computer has.
  • You are using an IP address as your Host ID. You may proceed past this warning message since this part of the installation only looks for a physical/MAC address as a valid Host ID. It does not mean you cannot use an IP address as your Host ID nor does it mean that the IP address is incorrect.
If you are using an IP address as the Host ID and you proceed with installation on a Windows machine, you may need to manually edit your license file after installation.
For example, the following SERVER line:
SERVER test-server 192.168.86.31 27000
Must be updated to:
SERVER test-server INTERNET=192.168.86.31 27000
Once the license.dat file is updated, you will be able to start the license manager.
The same information can be found here:

I hope this was helpful.
