Java Code Error 1618

Posted onby

Like many software, problems may occur in Java as well. Also, there are a lot of software applications which require Java as a dependency for the software application to function properly, especially in the Windows operating system environment.

What causes ‘Java error code 1618’? Like mentioned before, this error message caused by a clash in Microsoft Installer. However, there are also other reasons why. An exit code of 1619 is considered a failure. I use an identical advertisement for the 64-bit version of Java and it will install with no problems. The 32-bit version will install fine if I run the install script without SCCM. I'm not sure what you mean by that. This is what i am doing right now if i want to try to install REVIT 2019: - i double click on the shortcut icon of installement for REVIT 2019 (located in C: Autodesk Revit2019G1Win64bitTrialwien-US).

When using the stand-alone Java for the purpose of developing websites, desktop and mobile applications, Java developers require a framework as well as a run-time environment, which are called the Java Development Kit (JDK) and Java Runtime Environment (JRE), respectively. Sometimes, these are also needed by other software applications (such as Microsoft’s Skype) for carrying out the needed functionality on the Windows operating system platform.

However, there is one such error which generally occurs when a user tries to install Java on his/her machine that is powered by the Windows operating system. Here, users who are running Windows 7 and later on their desktop and laptop computers, might have encountered an error during the installation of Java. Now, during the installation of Java on Windows, the installation gets interrupted and then an error message is thrown on the user’s screen along with an error code, which is Java error code 1618.

Thus, since a lot of users have encountered this problem in the past many days and years, it now has a solution, where users can easily fix the error in Java on their Windows 7 and later editions of the operating system.

The cause of the Java error code 1618 and the solution to fix the issue has been described in this article.

At times, it may happen that when you are installing Java on your computer running Windows operating system, an error pops up at the end off the installation and interrupts the whole installation process.

The error message which usually pops up on the users’ computer screen is given below:


Java update did not complete

Error Code: 1618

Please refer to the Java Help Center for troubleshooting information or contact your system administrator.

The error message given above may occur due to the following reasons:

  1. Windows installer is disabled
  2. Windows installer is not functioning properly or is corrupt
  3. Windows operating system has been recently updated
  4. Certain needed settings and/or Windows configuration have been altered
  5. Some services are interrupting Java from being executed

These are some of the common reasons as to what causes the Java error code 1618 to occur unexpectedly on Windows 7 and later editions.

There are fixes available for the Java error code 1618.

Configure Windows updates

When you run the default automatic updates on your Windows-based desktop or laptop, several files, applications, and security patches also get downloaded from Microsoft center, which are then installed immediately in the background on your system. However, this often results in rendering other software programs and/or settings to malfunction.

For experienced Windows users, it is advised that you select the update options manually and install only what you need (when downloads are available), which includes ‘critical’ and ‘recommended’ system updates.

Only install applications that you need

Sometimes, installing too many software applications on your Windows machine may open the door to unwanted problems and issues. This might also affect other applications which are already installed on your system or the ones that you are trying to install at present.

Therefore, in order to keep your Windows configuration and other settings intact, it is advised that you install applications that you trust and prevent your system settings from being over-ridden.

Restart Windows installer service

The Windows installer service is required in order to install software applications on your Windows computer. So, if this service (which loads automatically at system start-up) is turned off or becomes corrupt, you will face challenges installing applications.

To make sure that the Windows installer service is working properly, access the Windows Services management window via Control Panel, then go to the Administrative Tools page, locate and restart the Windows Installer service. Then restart your computer and try installing the application again.

Do a clean system reboot

Last, but not the least, if all options fail, then you can perform a clean system reboot to fix the Java error code 1618 on your Windows machine. This method usually helps in fixing various problems that occur in Windows.

To do a clean system reboot, you are required to launch the System Configuration window via Run → Type msconfig in the search box and press the OK button or hit the Enter key. Now, go to the Services tab, check “Hide all Microsoft services” option at the bottom and then click the Disable button. Click the OK button and restart your computer.

  • be careful when installing programs;
  • avoid parallel installations;

1. End the Microsoft Installer Process

To tell the truth, a little patience is required when it comes to installing programs on your computer: for example, you are supposed to proceed with a Skype install only when no other installation processes are being executed. However, we understand you might need to use the app without any delay. In such a case, you will have to end the msiexec.exe process manually.

For this purpose, use Windows Task Manager:

  1. Ctrl+Alt+Del -> Task Manager
  2. Processes -> select the MSIEXEC.EXE process -> Click End Process
  3. Install Skype

Has the issue been resolved? If not, hurry up to give the following method a try.

2. Run Skype as an Administrator

If the error 1618 prevents Skype installation from being a success, you can try the following workaround:

Skype setup file -> Right-click on it -> Run as administrator

Did it work?

If you still encounter the ‘Another installation is already in progress’ message, keep working your way down.

3. Install Windows Updates

If your PC is acting weird (which includes generating the 1618 installation error), your system might need updating.

Make use of the built-in Windows Update feature:

  1. Windows logo key + I -> Update and Security -> Check for updates
  2. Let the available updates come through
  3. Wait for the installation process to complete
  4. Restart your PC

Now try to install Skype on your computer. If the frustrating 1618 error code is still here, consider tweaking your Windows registry.

4. Edit Your Registry

Whatever it takes, be extremely careful when editing your registry – even a minor mistake can damage your system and cause your PC to go haywire.

Therefore, we strongly recommend you to back up your registry before editing it:

  1. Windows logo key + R -> Type regedit.exe into the Run box-> Enter
  2. Registry Editor -> Select the registry keys and/or subkeys you want to back up -> File > Export ->Choose the location and name for the backup file -> Save

Now you can perform the necessary changes:

  1. Windows logo key + R -> Type ‘regedit’ into the Run box
  2. Navigate to HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionInstaller
  3. Find and delete PendingFileRenameOperations
  4. Move to HKEY_LOCAL_MACHINESOFTWAREMicrosoftUpdates
  5. Search for the UpdateExeVolatile entry -> Double-click on it -> Set it to 0

That is it.

6. Fix Your Drivers

Driver issues are brilliant at wreaking havoc on your computer. For instance, they can easily turn Skype installation into a nightmare. Therefore, mending your drivers might eliminate the annoying 1618 error code and give the green light to a successful Skype install.

In this regard, you can:

Use Driver Verifier to track down the misbehaving drivers

Start menu -> Type verifier -> Enter

Make use of Device Manager
