Some Windows users have reported getting this error when they try launching a Java program. If you don’t have Java installed on your PC, this error will occur. However, this error can pop up in certain other scenarios. It can happen due to missing system environment variables or a corrupted installation of Java. Nonetheless, this error can be fixed using some of the fixes mentioned in this post. So, check out.

If you get the Windows cannot find javaw.exe error message while launching Java-based software, use the following solutions to fix the error:

1. Make sure Java is installed on your PC.
2. Add the path of Javaw.exe to the Environment Variable Path.
3. Reinstall Java.

1] Make sure Java is installed on your PC

Since Java is required to run Java-based apps and software on Windows, ensure you have Java installed on your computer. Otherwise, you might run into errors like these.

2] Add the path of Javaw.exe to the Environment Variable Path

The next thing you should do to fix the error is to check whether Java is included in the System PATH Environment Variable. If not, manually add the path of Javaw.exe to the environment variable and then check if the error is gone. Here’s how to do that:

First, press the Win+R hotkey to open the Run command box and enter “sysdm.cpl” in the Open box to launch the System Properties window.

Now, move to the Advanced tab and then hit the Environment Variables button present at the bottom of the window.

After that, under the System variables section, select the Path variable and press the Edit button.

In the Edit environment variable window, press the New button and enter one of the below path:

C:\Program Files\Java\jre-1.8\bin

or

C:\Program Files (x86)\Java\jre-1.8\bin

The above path is where the “javaw.exe” file is present by default. And, jre-1.8 is the version. If you have installed Java in a customized location, enter the path accordingly.

You can also add the symbolic link javapath to avoid adjusting the path variable after each Java update. Add the below path to the above system variable:

C:\Program Files (x86)\Common Files\Oracle\Java\javapath

If the path variable is absent, click on the New button under the System variables section to open the New System Variable window. Next, enter “path” in the Variable name field and enter the Java installation location in the Variable value field. Once created, you can add the above-mentioned paths.

When done, press the OK button to save changes and exit the System Properties window.

Here’s how to do that:

First, open the Settings app using Win+I and move to the Apps tab from the left-side pane. After that, click on the Installed apps option.

Now, look for the Java application under the list of your installed apps and press the three-dot menu button attached to it.

Next, select the Uninstall option and then confirm the uninstallation to remove it from your PC.

When done, reboot your computer and download the latest version of Java from its official website.

Finally, install Java on your PC and see if the Windows cannot find ‘javaw.exe’ error is fixed now.

What is the difference between Javaw exe and java exe?

Both java.exe and javaw.exe can run Java programs. However, the main difference between the two is the way they interact with the operating system. The “java.exe” executable file used the command-line environment to run Java applications. It is primarily used to run apps that need a command-line interface (CLI). On the other hand, the javaw.exe executable can run Java programs without the console window or command prompt. It is mainly required for graphical user interface (GUI) based apps.

How do I find java exe?

Java is, by default, installed at the C:\Program Files\Java location on a 64-bit architecture. So, the java.exe file is present in a similar folder like C:\Program Files\Java\jre-1.8\bin.

If you cannot find this file or it is in a different location, you should check the device for malware.
This video will help you with the issue:

Step 1. Check if your computer is not infected with a virus

As we have already mentioned, the most frequent reason for this error is malware infection, so system check with anti-malware should help you to detect the cause and get rid of it.

Therefore, if you receive a pop-up window that informs about missing Javaw.exe error, you should download a reliable anti-spyware, such as Reimage Fortect, and initiate a full system check.

If the culprit of the error is not a virus, Javaw.exe error most probably is triggered by a corrupted Javaw.exe file. To check that, you should open Windows Task Manager and check your PC’s CPU usage. Actually, you should check CPU usage quite frequently. To do that, you have to:

1. Click Ctrl+Alt+Del at once and open Task Manager;
2. Open Processes tab and find the javaw.exe file.

The genuine javaw.exe file does not consume huge amount of memory, so if the file that you have found uses an excessive amount of memory, most probably you are encountering a fake one.

In case malware is not the culprit of the javaw.exe error, the problem was probably caused by old version of system files. To check and fix that, please try the following methods.

Step 2. Make sure that location to the Environment variable path is correct

1. Press Win+R keys.
2. Type sysdm.cpl in the Run window and click Enter.
3. Navigate to the Advanced tab.
4. Click on Environment Variable button at the end of the window.
5. In the category System Variables click New… button.

6. In the Variable name box enter Path.
7. In the Variable value type the correct path which by default is C:\\Program Files\\Java\\jre7\\bin for java 1.7.x on a 32-bit version of Windows, C:\\Program Files (x86)\\Java\\jre8\\bin for java 1.8.x on a 64-bit version of Windows, etc.

Step 3. Reinstall Java

First of all, you have to uninstall Java:

1. Open Control Panel.
2. Navigate to Uninstall a program (or Add/Remove Programs).
3. Find Java, select it and click Uninstall button.

Once you uninstall it, go to java.com website and download the latest version of the program which is compatible with your computer.

Step 4. Fix Windows Registry problems

The following steps require making changes to Windows Registry. We highly recommend creating backups of the Registry in case something goes wrong.

1. Click Win + R.
2. In the Run box, enter regedit and click Enter.
3. Navigate to HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\App Paths\\javaws.exe.

PS: I took a peek at the Windows registry, and didn’t notice anything immediately looking abnormal. For example, it shows JavaHome to be set to C:\Program Files\Java\jre1.8.0_181 , which looks good.
