1. Reinstall or update Java
Java is an important part of several programs, including browsers like Google Chrome and Mozilla Firefox. If you are having trouble getting Java to work properly, it could mean that you don’t have the latest version installed. If you’ve already tried updating Java, try uninstalling it again. This might solve the issue.
2. Add the path to Javaw.exe to the Environment Variable Path.
If you want to use the JDK 8 version of Java, it must be installed into a specific directory. If you do not know where the installation folder is, here are some steps to help you out.
1. Open the Control Panel.
2. Click System and Maintenance.
3. Select Advanced System Settings.
4. In the left pane, select Environment Variables.
5. Locate the PATH variable under User variables.
6. Right-click the PATH variable and choose Edit.
3. Scan for malware
Malicious software like viruses, spyware, adware, etc., cause many different kinds of issues on PCs. This article explains how you can use free tools to scan your computer for malware.
Free trial offers of Norton AntiVirus are now available for download. These offer a 30 day free trial period. After this period, there is no cost involved in using the product. You can try it out for free. If you decide to continue using the program, you will pay $99 per year. However, if you do not want to continue using the product, you can cancel within the 30 days and receive a full refund.
The best way to protect yourself against malicious software is to install security programs on your device. There are several types of antivirus products available. Some of them are free while others require payment. All of them work differently and perform different functions. You can choose one based on what type of threat you face most often. For example, some people tend to encounter more threats related to email attachments, while others are more likely to come across ransomware attacks.
You can find anti-malware solutions on the web. One such solution is Norton AntiVirus. You can download the application directly from the Norton website. Once installed, you can run scans manually or schedule regular scans. In addition, you can set up alerts to notify you whenever suspicious files are detected.
Another option is Kaspersky Internet Security. Like Norton, Kaspersky provides both free and paid options. The free version includes basic features and does not provide real-time protection. However, it does include virus scanning and file integrity monitoring. Users can upgrade to the premium version for additional benefits like automatic updating, cloud backup, parental controls, etc.
Google Chrome is another popular browser choice. Its built-in extensions allow users to easily block popups, manage cookies, and even automatically delete old logins. A few add-ons can improve browsing experience too. For example, you can enable Safe Browsing to prevent phishing attempts and trackers. Another extension allows you to quickly access bookmarks and open tabs.
If you frequently use public Wi-Fi networks, consider installing the OpenVPN client. It creates secure tunnels over unencrypted connections. The VPN encrypts your data and hides it from snoopers. As long as you connect to a trusted network, your identity cannot be stolen.
4. Run System File Checker (SFC) scan
The Windows Error Recovery tool is designed to help fix problems related to system files, such as missing or corrupt files, damaged DLLs, and invalid registry keys. If it encounters errors while running, it displays a list of possible solutions. You can select one of those options or use the command prompt to run a full scan of your computer. This will take longer than clicking through the wizard, but it will ensure that no important data is lost.
If you are unable to open your favorite program, try downloading the latest version of the software. Sometimes older versions contain bugs that prevent newer programs from working properly.

Frequently Asked Questions
How do I run a JAR file?
Running a Java Archive (JAR) file is very similar to running a.zip file. Both files contain compiled code that can be executed when opened. However, unlike zip files, JAR files cannot be unzipped. They must be extracted first before being used.
Here’s a step-by-step guide to creating a JAR file:
1. Create a folder named “jarfile” inside the same directory as your source code.
2. Copy all of the source code files into the jarfile folder.
3. Right click on the jarfile folder and select properties.
4. Click the tab labeled “compile” and make sure the box next to “build automatically” is checked.
5. Save the changes and exit the window.
6. Double click on the jarfile icon to open it.
7. Select the “Extract All” button.
8. Wait until the extraction process completes.
9. Close the window.
What are the requirements to run a JAR file?
JAR files are used to store Java applications. They are similar to ZIP files but contain additional information like classpath entries, manifest files, and so forth.
Here’s a quick overview of some of the things you’ll find inside a JAR file:
1. Manifest Files
Manifest files describe the contents of the archive. Each manifest file contains a list of classes and resources packaged within the archive. For example, the manifest file for the HelloWorld application below lists the main class, package name, version number, and copyright notice.
Main Class Name: com/example/HelloWorld
Package Name: com.example
Version Number: 1.0
Copyright Notice: Copyright © 2017 Example Inc. All rights reserved.
2. Class Path Entries
Class path entries provide instructions for locating the required classes when loading the archive. These entries point to specific locations on the local machine, networked machines, or remote servers.
For example, the following class path entry instructs the Java Virtual Machine to look for the HelloWorld class in the directory C:\Users\joe\Desktop\JavaProjects\.
Resources are files stored within the archive. For instance, the resource named “hello.txt” is located in the same folder as the manifest file. When the archive is loaded, the Java Virtual Machine automatically loads the resource.
Why does my application fail to start?
Your software application may fail to start when you try to run it. There are several reasons why this happens. Here are some common causes of startup failure:
1. Missing DLL files
Missing DLL files cause your application to crash during startup. To fix this issue, download the missing DLL files from Microsoft and install them in the correct location.
2. Invalid registry settings
Invalid registry settings prevent your application from starting correctly. Check the following registry keys for invalid values: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon; HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce; HKEY_CURSOR\Software\Microsoft\Office\12.0\Common\Startup; HKEY_CUSTOMERS\Software\Microsoft\OEM\12.0\Setup; HKEY_USERS\Software\Microsoft Office\12.0\common\startup; HKEY_USRPROFILES\Software\Microsoft\office\12.0\setup; HKEY_USRSYSTEMDRIVES\Software\Microsoft\windows\currentversion\runonce; HKEY_USRCACHE\Software\Microsoft\Excel\12.0\Cache; HKEY_USRLOCALS\Software\Microsoft\Word\12.0\cache; HKEY_USRPACKAGES\Software\Microsoft\Project\12.0\packages; HKEY_USRDATABASES\Software\Microsoft SQL Server\90\Tools\Shell\Binn; HKEY_USRBINFILES\Software\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe; HKEY_USRTEXTSHARE\Software\Microsoft\VisualStudio\9.0\TextTemplating\VSSDK\Shared; HKEY_USRRUNTIME\Software\Microsoft\VSCommon\14.0\Runtime\Settings\Default; HKEY_USROOT\Software\Microsoft\MSXML\CoreConverters\14.0\Settings; HKEY_USREFS\Software\Microsoft\SQL Server\90\Tools\\Shell\Binn;
3. Incorrectly installed applications
Some applications conflict with each other. For example, you may have both MS Word and Excel open at the same time. When you attempt to launch either of these applications, you receive an error message stating that another instance of the application is running.
4. Uninstalled applications
Uninstalled applications can also cause problems. For example, you uninstall MS Access but leave MS FrontPage still installed. When you attempt to run FrontPage, you receive an error stating that the application cannot be started due to incompatibility issues.
5. Malware infections
Malware infections can cause your computer to stop responding properly. They can slow down your system performance and make it difficult to complete certain tasks.
6. Hardware failures
Hardware failures can cause your computer to shut down unexpectedly. These hardware failures include faulty memory modules, bad power supplies, defective video cards, etc.
7. Software conflicts
Conflicts between different versions of programs can cause your computer to malfunction. For example, you have two instances of MS Outlook open at the same time, and one of them crashes.
