# Update Failure Application Used by Another Process ## Problem You are trying to deploy Java updates but the deployment fails with the error message **"Update Failure Application used by another process"**. ## Cause You might face any of the above mentioned scenarios due to one of the following: - Users are logged in and have a Java application open on their computer. - The Java Quick Starter application (jqs.exe) is running. **Note**: If the installation of the updates fails it will remove the old version of the product. ## Resolution It is preferable to install Java updates while no users are logged in, no Java-based application is running, and while the Java Quick Starter application (jqs.exe) is not running. You can follow the best practices mentioned below to increase the success ratio while deploying Java updates. ### Best Practices - It is recommended to deploy the Java updates during system startup while no user is logged on. - It is recommended to schedule the Java updates while no Java application is running. - It is recommended to use Software Deployment with the **'RUN AS'** option enabled so that no other configuration is deployed at the same time. This would increase the success rate of deploying Java updates. **Note**: It is also recommended to install Flash Player updates during system startup. Flash update fails if any application that uses Flash Player is running while the deployment is in progress. So ensure that all web browsers are closed before installing Flash Player updates. **Applies to:** Patch Deployment, Patch Installation Failure, Patch Installation Error, Patch Errors **Keywords:** Patch Installation, Patch Management, Patch Deployment Error, Patch Installation Failure
