Error occurred launching Android Studio

Hello experts,
I have Windows 7 64-bit operating system with 8 GB Ram and 250GB hard disk. I install Android Studio latest version and Java SDK in the system it was successful without any error. I got an error message when I try to launch the Android Studio for the first time. I do not have any idea why it is happening. Please help me to fix the missing dll file in the computer. Thanks.

Error launching Android Studio
Failed to load JVM DLL C:Program FilesJavajdk1.7.0_25jre.
If you already have a 32-bit JDK installed, define a JAVA_HOME variable in
Computer>System Properties>System Settings>Environment Variables.
OK
