    JVM Launcher displays Unable to access jar file MP3Rocket.jar

    I want to use MP3Rocket for downloading music files from the internet. I had downloaded mp3rocket and installed it on to my system. I have installed it as it was directed to me while installing it. After installing I was not able to use it as it displays an error message saying unable to access jar file lib\MP3Rocket.jar. It says the error is because of the Java Virtual Machine Launcher. Kindly help as I want to fix this problem. Your suggestions will be appreciated.

    Try downloading the MP3Rocket file again as there might be a chance where your downloading was not exact and you ended up for corrupt installation of the files. To resolve this go to the mp3rocketís website and try to download the latest or updated version of it. After it is downloaded install the software as directed to you. I hope this will resolve your queries related to it. You can also verify the java version which you are using on to its website.

    As your software would require running on JRE platform. Try downloading the latest JRE (Java Runtime Environment) software available on sun website which supports a jar file. Or you can just go to the Google website and type over the search bar. Over there you will find the various versions available for download. After downloading the file you just need to double click on it after going to its location. Now it will install the JRE on to your system and do as it directs you. Now I guess your problem is resolved and you are able to run your jar file.
