Unable to Run Jmeter in my windows system

I am getting the below error while launching Jmeter

java.util.prefs.WindowsPreferences WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0x80000002. Windows RegCreateKeyEx(...) returned error code 5. Server failed to start: java.rmi.server.ExportException: Listen failed on port: 0; nested exception is: java.io.FileNotFoundException: rmi_keystore.jks (The system cannot find the file specified) An error occurred: Listen failed on port: 0; nested exception is: java.io.FileNotFoundException: rmi_keystore.jks (The system cannot find the file specified) errorlevel=1 Press any key to continue . . .

It seems you're trying to run JMeter in distributed mode, the error is about missing rmi_keystore.jks file which is required for secure communication between master and slaves which is default behavior since JMeter 4.0

You need to launch create-rmi-keystore.bat file and supply the required information:

See Setting UP SSL chapter for more details

Alternatively you can add the next line to user.properties file:

server.rmi.ssl.disable=true

• it needs to be done on master and all remote slaves
• JMeter restart will be required to pick the property up

This setting will disable secure communication between JMeter master and slaves and you will not have to create the keystore.
