damaged Java program on the computer;
corrupted Java registry;

In the process of their work, many created under Windows applications use libraries included in built-in or separately installed frameworks like . One of the most common components of this kind is Java, a software platform developed by Sun. At one time, Java played a significant role in software adaptation, serving as a kind of spacer between hardware, operating system and software environment. Today this software is no longer in such demand, however, there are still many applications that need it.

If during installation a program requires Java, you should download it latest version from the official website and install on PC as normal application. Usually, the installation of the package goes without problems, but in some cases, at this stage you may get an unpleasant surprise, or rather error 1603, indicating an installation failure.

The main causes of the error

You most often encounter this problem when reinstalling or Java update. In general, error code 1603 is quite typical mistake installation and occurs not only when installing Java, but also when working with other programs. The causes of failure most often lie in damage installation files, process interruption, incorrect overwriting or deletion of associated registry keys. In addition, Error code 1603 Java error can be caused by incomplete Windows cumulative updates.

What to do if you receive a Java installation error

So, you are faced with error code 1603 Java. What to do? The most effective, and therefore correct, solution in this case would be to completely reinstall the component. However, to remove an old or corrupted version of Java, it is better to use special utility Java Uninstall Tool, which can be downloaded from the official website www.java.com/ru/download/uninstalltool.jsp.

Also great for uninstallation third party applications, such as Wise Program Uninstaller or Total Uninstall. Unlike standard means uninstalling programs, these applications allow you to find and delete “tails” remaining after uninstallation - temporary files, folders and registry keys, which often cause conflicts during a new installation.

Advanced users can perform additional searches for junk directories and registry keys using the keyword "Java", but this is a rather risky operation since there is a high chance of deleting something important. After uninstalling the platform, you should restart your computer.

Removing potentially conflicting updates

If shortly before the appearance errors error code 1603 When installing Java, you installed cumulative updates, try removing them. In particular, check to see if you have the KB2918614 update package on your computer; if so, uninstall it.

Changing the installation location and checking permissions

Error 1603 during the Java installation process sometimes occurs due to the System not having rights to the directory in which the application is installed. You will also encounter problems if you try to install Java on a removable drive, an encrypted drive, or a similarly protected folder. We do not recommend changing access rights to system directories; instead, create a separate folder in the root of drive C or D and make sure that the SYSTEM user has full rights to it.

Now you can start reinstalling. Download the offline Java installer from the official website because it is the most reliable option. Before running the installer executable, open Task Manager and check for the presence of the process MSIEXEC.EXE. If it is running, terminate it. Launch the Java installer, check the “Change destination folder” option and click “Install”.

In the next wizard window, click the “Change” button, specify the path to an alternative installation location and install the platform as usual.

Disabling Java Content in the Browser

This method does not require radical removal of an old or corrupted version of Java, but it can be tried if error 1603 occurs when upgrading Java over an earlier version. Open the Java Control Panel (via search), switch to the Security tab and uncheck the “Enable Java Content for browser...” checkbox. After saving your settings, download the offline Java installation package and install it. Once the procedure is complete, activate the previously disabled setting.

The first method is to reboot

Sometimes, a simple reboot is enough to fix the error.
Restart the system, download the Java package from the official website and run the installation.

The second method is to disable Java in browsers

If the previous method did not work, move on to the next step.
Let's try to disable the use of Java content in the browser.

To do this, go to the Panel Windows management and find the Security item.
Uncheck the box that is responsible for displaying content in browsers.
Afterwards, we reboot the computer and try to install Java again.

The third method is cleaning “tails” and registry entries

There is a high probability that you already have more than old version Java, or was removed incorrectly, in this case it is worth cleaning up the so-called “tails”. This operation can be performed using the standard uninstall tool in the taskbar, but it is better to use a third-party software, which is specially created for such tasks. The most popular are CCleaner and Revo Uninstaller.

The programs are intuitive clear interface and will not cause difficulties in use.

The most serious reason is the occurrence of an error due to damaged registry entries. If you have not encountered the work of the registry before, then it is better not to start honing your skills in this situation. You risk increasing the number of errors and causing the system to become unstable.

If you still decide, do not forget, before you start editing the registry, to make a backup copy of Windows using standard tools or third-party software.

Let's start the process, it is best to use the WinThruster program.

Find all Java-related entries and then delete or restore. Software, before any actions, does backups in .reg format, so that in case of failure you can return everything back.

The fourth method is to check the system for viruses and malware

There is a possibility that the system has been infected with malware and thus makes the installation of the Java package impossible. In Windows 10, it is possible to scan with a standard antivirus.
Checking will not hurt in any case, because it affects the performance of your operating system.
