jawaw.exe Application Errors? [Solved]

If you are having trouble running Java applications on Windows 10, here are some troubleshooting steps you might want to try.

C:\Program Files\Java\jdk1.8.0_151\bin;%JAVA_HOME%\bin

3. Restart the computer.

4. Try launching the application again.

5. If you still cannot run the application, please contact us via our support form.

What should I do if Windows 10 doesn’t have javaw.exe?

Java Web Start is a way of installing applications without having to download the application file. This is particularly useful if you are trying to run a program that requires Java Runtime Environment (JRE). JRE is required to run some programs such as Minecraft, Chrome, Firefox, etc. However, it is possible to use Java Web Start even if you don’t have JRE installed. In fact, there are several ways to make sure that Java Web Start works properly.

If you’re running Windows 7 or 8, you’ll probably find that java.exe is already present on your system. If you’re running Windows 10, however, you might not see java.exe. If you receive a 404 error, then Java Web Start isn’t working.

Scroll down to Java SE Development Kit (JDK), select it, and click OK. Now restart your PC.

You can now use Java Web Start again.

2. The Environment Variable Path should now contain the Javaw.exe Path.

If you are having trouble locating Java 7 Runtime Environment (JRE), follow the steps below.

1. Open the command prompt window.

2. Type “cmd”.

3. Press Enter key.

4. In the Command Prompt window, type “set”, press Enter key.

5. In the Command Prompt Window, type “path”, press Enter key. You will see something like this:

C:\Program Files\Java\jre7;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\ProgramData\Oracle\Java\javapath;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\WOW64\System32\WindowsApps;c:\Users\Administrator\AppData\LocalLow\Sun\Java\Deployment_1480653617\bin

Uninstalling Java on Previous Versions of Windows:

Installing Java

Java is one of the most popular programming languages used today. While it is free to use, there are many different versions of the software available. Some people prefer to download the full version while others opt for the lightest weight version possible. If you want to install Java, here are some things to consider.

Downloading the entire package will save you time because you won’t have to download each individual component separately. However, you might end up having multiple files on your computer. This could cause problems down the road. For example, if you delete one of those files, you’ll lose access to the program.

If you’re looking for a lightweight version of Java, try OpenJDK. You can find it online.

Offline Java Installation

If you want to install Java without internet access, follow these steps:

1. Download the latest version of Java from Oracle’s website.

2. Extract the downloaded archive file into a folder of your choice.

3. Open the extracted folder and double-click on jdk-8u40-linux-x64.bin. This will start the installation process.

4. Follow the instructions displayed on screen.

5. Once done, restart your computer.

6. Check whether Java is installed successfully.

Online Java Installation

Before installing Java online, make sure your firewall allows downloads. If you are having trouble getting it to work, try saving the download locally. You’ll want to double-click on the downloaded file to start the installation process. Once the installation completes, you’ll be able to use the Java version command to verify whether the program installed correctly. After you’ve finished the installation, restart your computer to ensure that the changes take effect.
