1. Check You’re Installing the Right Java Version for Your Platform
First, make sure that you’re not installing 64-bit Java on a 32-bit system. If you are, that’s probably why Java doesn’t install. You can select to download Windows x86 Offline, which is the 32-bit version, from this page. You can check whether your system is 32 or 64-bit as follows.
- Press the Windows 10 Cortana taskbar button.
- Input the keyword ‘system’ in the search box.
- Then click About your PC to open the window directly below.
- Scroll down to the System type specification that tells you if the platform is 64 or 32-bit.
Another thing to note is whether your currently installed Java SDK is 32 or 64-bit. There can be a 64 and 32-bit conflict if you’re trying to update Java with a 32-bit version to replace a 64-bit Java SDK or the other way around. So install a 64-bit Java version to replace an outdated 64-bit version, or update 32-bit Java with the latest 32-bit version.
2. Install Java as Administrator
Installing software as an administrator can resolve installation issues. As such, try installing the latest Java version as an administrator. To do that, right-click the latest Java installer and select Run as administrator to launch the setup wizard.
3. Uninstall the Previous Java Version First
Uninstalling the previous Java version first ensures there are no 32 or 64-bit conflicts when you try to install the latest version. Add a third-party uninstaller to Windows with which you can completely remove Java. This is how you can uninstall Java with the freeware Advanced Uninstaller PRO 12 for Windows.
- Press the Download Now button on this homepage to save Advanced Uninstaller PRO 12’s to Windows.
- Open the Advanced Uninstaller PRO 12 setup wizard to install the software.
- Open Advanced Uninstaller PRO 12, click General Tools and Uninstall Programs to open the window directly below.
- Select Java and press the Uninstall button.
- Click the Use the leftover scanner radio button on the dialog box window shown directly below.
- Press the Yes button to uninstall Java.
- Select all the registry entries when the Application uninstall cleanup window opens, and press the Next button.
- Restart Windows after uninstalling Java.
- Install the latest Java version with the 32 or 64-bit Windows offline installers.
4. Switch Off Anti-Virus Software
Anti-virus software might be blocking your Java deployment. To ensure that isn’t the case, you can temporarily disable many anti-virus utilities by right-clicking their system tray icons and selecting a disable option. Alternatively, temporarily remove the anti-virus software from the Windows startup and then reboot. This is how you can disable anti-virus utilities on the Task Manager’s Start-up tab.
- To open the Task Manager, right-click the taskbar and select Task Manager.
- Click the Start-up tab, and then select your anti-virus software.
- Press the Disable button to exclude the software from the startup.
- Install Java after restarting Windows.
5. Close Your Browser and Other Software Running Java
Always close software before installing Java. There might be programs running Java when you try to install the latest version. Close your browser after downloading the Java installer. Close all other software windows on the taskbar. In addition, check if your system tray (notification area) includes any third-party software icons. If so, close the programs included on the system tray.
6. Disable Java Content
Closing browsers might not always be enough. Disabling all Java content via the Control Panel is also among the better fixes for Java error 1603. You can disable Java content as follows.
- First, press the Windows key + R keyboard shortcut.
- Enter ‘Control Panel’ in Run and press Return to open the window shown directly below.
- Click Java to open its control panel.
- Select the Security tab on the Java Control Panel.
- Deselect the Enable Java content in browser option if that setting is selected.
- Click the Apply and OK buttons to confirm.
- Select the Enable Java content in browser option again after updating Java.
7. Open the Program Install and Uninstall Troubleshooter
Although Windows doesn’t include a program install troubleshooter, you can still download the Program Install and Uninstall troubleshooter. That troubleshooter might resolve the Java error 1603. You can add the troubleshooter to Windows 10 by clicking the Download button on this webpage.
Then open the folder you saved the installer to, and click MicrosoftProgram_Install_and_Uninstall.meta.diagcab to open the window shown in the snapshot directly below.
8. Don’t Install Java With LogMeIn
The Java error 1603 has occurred for LogMeIn users when attempting to install Java remotely. LogMeIn users have discovered that the installation error can be due to the LogMeIn remote desktop software.
So if you’re utilizing LogMeIn when installing Java, ditch that software and install Java on the PC without remote desktop software. If you really need remote desktop software to install Java, check out some of the alternatives to LogMeIn.
