What are javap.exe Error Messages?

javap.exe Runtime Errors

Runtime errors are NetBeans errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these EXE errors are triggered when javap.exe is attempted to be loaded either when NetBeans is starting up, or in some cases already running. Runtime errors are the most common form of EXE error you will encounter using NetBeans.

In most cases, javap.exe runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these javap.exe error messages mean that NetBeans was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, NetBeans will be unable to start without resolving these errors.

Some of the most common javap.exe errors include:

javap.exe - Bad Image.
javap.exe Application Error.
javap.exe could not be found.
javap.exe could not be installed.
javap.exe could not be launched. Class not registered.
javap.exe could not be started.
javap.exe failed to initialize properly.
javap.exe has encountered a problem and needs to close. We are sorry for the inconvenience.
javap.exe is not a valid Win32 application.
javap.exe is not running.
Cannot find javap.exe.
Error starting program: javap.exe.
Faulting Application Path: javap.exe.
The file javap.exe is missing or corrupt.
Windows failed to start - javap.exe.

System Error

The program can’t start because javap.exe is missing from your computer. Try reinstalling the program to fix this problem.

Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

Finding the source of the javap.exe error is key to properly resolving these errors. Although most of these EXE errors affecting javap.exe will happen during startup, occasionally you will encounter a runtime error while using OpenJDK Platform 13. This can occur due to poor programming on behalf of Oracle Corporation, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of javap.exe errors can occur if it has been accidentally moved, deleted, or corrupted by a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

How to Fix javap.exe Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your javap.exe issue. These troubleshooting steps are listed in the recommended order of execution.

Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

Hit the Windows Start button
When you see the search box, type "System Restore" and press "ENTER".
In the search results, find and click System Restore.
Please enter the administrator password (if applicable / prompted).
Follow the steps in the System Restore Wizard to choose a relevant restore point.
Restore your computer to that backup image.

If the Step 1 fails to resolve the javap.exe error, please proceed to the Step 2 below.

Step 2: If recently installed NetBeans (or related software), uninstall then try reinstalling NetBeans software.

You can uninstall NetBeans software by following these instructions (Windows XP, Vista, 7, 8, and 10):

Hit the Windows Start button
In the search box, type "Uninstall" and press "ENTER".
In the search results, find and click "Add or Remove Programs"
Find the entry for NetBeans 9 and click "Uninstall"
Follow the prompts for uninstallation.

After the software has been fully uninstalled, restart your PC and reinstall NetBeans software.

If this Step 2 fails as well, please proceed to the Step 3 below.

NetBeans 9

Sun Microsystems

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many javap.exe error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

Hit the Windows Start button
In the search box, type "Update" and press "ENTER".
In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
If updates are available for download, click "Install Updates".
After the update is completed, restart your PC.

If Windows Update failed to resolve the javap.exe error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

If Those Steps Fail: Download and Replace Your javap.exe File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate javap.exe file version. We maintain a comprehensive database of 100% malware-free javap.exe files for every applicable version of NetBeans. Please follow the steps below to download and properly replace you file:

Locate your Windows operating system version in the list of below "Download javap.exe Files".
Click the appropriate "Download Now" button and download your Windows file version.
Copy this file to the appropriate NetBeans folder location:

Windows 10: C:\Program Files\Java\jdk1.7.0_40\bin\
Windows 10: C:\Program Files (x86)\Java\jdk1.7.0_40\bin\
Windows 10: C:\Program Files\Java\jdk-12\bin\
Windows 10: C:\Program Files (x86)\Java\jdk1.5.0_22\bin\
Windows 10: C:\Program Files (x86)\Java\jdk1.8.0_231\bin\
Show 1 more directory +
Windows 10: C:\Program Files\Java\jdk-13.0.2\bin\
Restart your computer.

If this final step has failed and you're still encountering the error, you're only remaining option is to do a clean installation of Windows 10.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve javap.exe problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.

Download javap.exe Files (Malware-Tested 100% Clean)

CAUTION : We strongly advise against downloading and copying javap.exe to your appropriate Windows system directory. Sun Microsystems typically does not release NetBeans EXE files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing javap.exe and all other EXE files for NetBeans. An incorrectly installed EXE file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
