  2. Click on Start Task Manager
  3. Click on the Processes tab
  4. Find and left-click on MSIEXEC.MSI in the list
  5. Click End Process
  6. Try installing Java now

If that doesn’t work then move on to the next fix.

  1. Restart your computer (turn it off, then turn it on)
  2. Download the offline Java installer: https://www.java.com/en/download/windows_offline.jsp

  1. You’re a life-saver.
    I didn’t find any “MSIEXEC.MSI” process in my Windows 7 Task Manager, but there was one named “MSIEXEC.EXE”. Holding my breath and praying to the gods, I terminated that process, then tried installing Java again and Bingo! It worked! Java installed successfully.
    However, the internet stopped working, but a system restart fixed that.
    I had spent half the night trying to install Java, but error 1618 kept popping up. Even the Java website had insane and convoluted solutions, didn’t even list that error number.

    I want you to know that your efforts are not in vain, they are appreciated by many like me, some halfway across the world.
    Thank you
