Java Error opening registry key
(16 answers)
Closed 4 years ago.
When I run on console javac -version, I get the version number as 11.0.2, but when I run java -version I get the following error:
Error: opening registry key 'Software\JavaSoft\Java Runtime Environment'
Error: could not find java.dll
Error: Could not find Java SE Runtime Environment.
What should I do about this?
Which version of JRE do I need to install for JDK 11.0.2,so that I won't get any compatibility issues which executing java code?
Check path.
To make sure that Windows can find the Java compiler and interpreter:
Select Start -> Computer -> System Properties -> Advanced system
settings -> Environment Variables -> System variables -> PATH.
Prepend C:\Program Files\Java\jdk1.x.x\bin to the beginning of the PATH variable.

I am using a 32 bit windows 7 OS and I have installed JDK 8 as it was the only available JDK version for a 32 bit system. I have also given the path in the environment variables. But, when I am trying to check the java version in the command prompt typing java --version, I am getting a fatal error.
You should double check if your path variable is set correctly. It should point to the ...\bin\ directory where the 'java.exe' is located. Because thats whats called with 'java --version'.

I'm trying to run a java application that I have compiled using the IntelliJ IDEA, by the commandline running the following command:
java myApp.Main
This gives me the following error:
"Exception in thread "main" java.lang.UnsupportedClassVersionError: FlightConverter/Main has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0"
In IntelliJ the JRE set to run in the run configuration is: /Java/jdk-11.0.3, but I get the error above when I try to run it. When i type java -version in cmd I get "1.8.0_211"
I cant really seem to find out how to update my current JRE to match what is used by the compiler either? It seems I'm only able to find JRE 8.xx online
I'm sure you can get location of java 8 from local system and set that as a compiler in IntellIJ IDE.. This way both your system and IDE works only on Java 8 and everything will work fine...
Hope this helps...

Eclipse - no Java (JRE) / (JDK) … no virtual machine
I am trying to get Eclipse Indigo to re-Start on my computer - i have run it before with no problems but now i getting error like this;
A java Runtime Environment (JRE) or Java Development kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations: C:\eclipse\jre\javaw.exe javaw.exe in your current PATH
How can i rectify this problem?
You can specify JVM in eclipse.ini file at the Eclipse root folder, like this:
-vm
C:\java\jdk1.6.0_24\bin\javaw.exe
This line must be placed before -vmargs options.
and for Linux
-vm
/..java address../bin/java
Try following:
Look at your filesystem and make sure a java instance is installed in the mentioned path
Open Eclipse and check the general preferences from Eclipse. Under 'Java' -> 'Installed JREs' must be a specified JDK configured.
Next, open the general preferences 'Java' -> 'Build Path' -> 'classpath Variables' and look is there the jdk instance mentioned. If not, open dthe control settings from windows and add the variable 'Java_Home'.
