1. Restart Windows Installer Service

You should make sure that the Windows Installer service is running to run the Java installation. Follow the above steps and start the service in case it is stopped.

2. Download Java offline installer

Chances are the Java installer is unable to fetch the installation files required to complete the installation. In this case, we would suggest you download the Java offline installer.

The benefit of using an offline installer is that it will download the entire package, i.e., the installation files and other important program-related files required for a successful installation. Once you have downloaded the offline installer, you can install the program without the internet.

All you need to do is disable the Windows Defender Firewall by following the above steps. We would suggest you turn Firewall back on when the issue has been resolved.

Several users have reported that updating their PC with the latest available update resolved the problem. Moreover, this issue was also associated with a specific version of the Windows 10 update.

Reportedly, the Windows 10 update version KB2918614 broke the Windows Installer and hence caused multiple issues including the Java error code 1618.

5. Clean boot your PC

When you perform a clean boot, your PC boots up with minimal drivers and programs that are the only essential ones required for the PC to function.

This also prevents the situation where a third-party program might be conflicting with the Java installation and trigger the Java error code 1618.
