Oracle Fusion Middleware 12c (12.1.3) requires a minimum of JDK 7.0 Update 55 or later. If you have an older version please update the JDK.
Let’s say your JDK is installed in:
C:\Program Files\Java\jdk1.7.0_xx
Search for cmd.exe in the Start menu. Right-click the cmd.exe and select Run as Administrator. In the prompt run the following command to set the JAVA_HOME:
SET JAVA_HOME="C:\Program Files\Java\jdk1.7.0_xx"
Using the command prompt, navigate to the directory where you unzipped the jar files.
Launch the installation wizard with the appropriate command.
%JAVA_HOME%/bin/java.exe -jar fmw_12.1.3.0.0_soa_quickstart.jar
