Windows cannot find ‘javaw’. Make sure you typed the name correctly, and then try again.

Cause

Providing JRE (Java Runtime Environment) is installed on the machine, most likely reason is that .bat script tries to find javaw.exe in a wrong location. For example it’s looking in Program Files but javaw.exe resides in Program Files(x86)

Resolution

Option 1

Open .bat script and search for javaw. Try replacing javaw with full path to the executable . For example “C:\Program Files (x86)\Java\jre7\bin\javaw.exe”

Option 2

Add javaw.exe path to PATHSystem Variable

• Computer > Properties > Advanced System Settings
• Change to Advanced tab
• Click on Environment Variables
• In System Variables section scroll down and double click on Path
• At the very end add ;C:\Program Files (x86)\Java\jre7\bin (or other valid path to javaw.exe)
  Don’t forget semi column, it separates path values.

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.

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.
