I have downloaded jbpm-installer-3.2.7.jar
but I don't know how to install or run the file.
If I double click on it, it opens in winrar
. I tried installing through command prompt, but I got the following errors:
C:\Documents and Settings\ccuser\Desktop\manoj>java -jar jbpm-installer-3.2.7.jar
Exception in thread "main" java.lang.UnsupportedClassVersionError: com/izforge/izpack/installer/Installer (Unsupported major.minor version 49.0)

This question is related to
java
installation
jar
executable-jar
If double-clicking on it brings up WinRAR, you need to change the program you are running it with. You can right-click on it and click "Open with". Java should be listed in there.
However, you must first upgrade your Java version to be compatible with that JAR.
Open up a command prompt and type java -jar jbpm-installer-3.2.7.jar
To run usually click and it should run, that is if you have java installed. If not get java from here
Sorry thought it was more general open a command prompt and type java -jar jbpm-installer-3.2.7.jar
