  4. Once you are able to locate the service, right-click on it. Choose the ‘End process’ option from the list. 

After doing this, go to the Java Installer and try to install Java once again. If ending the ‘MSIEXEC.EXE’ doesn’t solve the Java error code 1618, then you can restart the service. 

How to Restart the Service?

Procedure 3: Check for the Windows Update

Microsoft provides frequent updates for Windows Installer to improve its features and remove problems and bugs. But, according to some tech specialists, the Windows Update version KB2918614 can corrupt the Windows Installer. 

It may happen because of the registry problems or owing to the overall structure. You can solve it easily by downloading the latest version.
