Windows 10 adds many new features and functions to the operating system. Some of these new features make Windows 10 a faster and more powerful operating system than previous versions of Windows. However, Windows 10 also has some limitations, including the “No JVM Could be Found” error message that most Windows 10 users may encounter.
A reminder to all Windows 10 users: if you encounter this error when running a Java application, it is most likely because you have not enabled the Java Runtime Environment (JRE) in Windows Settings > Apps > Apps and Features > Enable or Disable Windows Features. If you find that one or more of your Java apps are not working properly, follow the steps described here to enable JRE in Windows 10.
In Windows 10, a common error message appears when you start a Java program: “Failed to find JVM (Java Virtual Machine).” This error can occur if your Windows 10 is configured to prevent unsigned Java applets from running.
What causes the “No JVM Could be Found” error message?
In most cases, this problem is related to an incompatible version of Java. In most cases, the affected users install the wrong version of Java, which causes this error in the application. However, in some cases, the error “No JVM could be found on your system (Exe4j_Java_Home)” also occurs due to an incorrect Java environment variable.
