Running Adobe Flash Builder on Win and Mac with Java 7/8 (UPDATED)

By Krati Rastogi and Vivek Kumar

Adobe® Flash® Builder® 4.7, which is an Integrated Development Environment (IDE) for developing games and applications using ActionScript and Flex framework runs on Java 6. If you do not have Java 6 on your machine Flash Builder does not launch and instead displays this error.

Steps to follow on Windows

1. Install Java 1.7/1.8.
2. Copy the jre7/jre8 folder inside the Java folder. Replace the jre folder inside flash builder installation folder with the copied one.
3. Restart Flash Builder.

Steps to follow on Mac

1. 1. Set your JAVA_HOME to Java 7 or Java 8 as per the correct paths on your machine.

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_91.jdk/Contents/Home

1. 1. Open JVM’s Info.plist at $JAVA_HOME/../Info.plist and add the highlighted lines to JVMCapabilities array:
   2. Create a symlink for libjvm.dylib as follows:

sudo mkdir –p /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/bundle/Libraries
sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/jre/lib/server/libjvm.dylib /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/bundle/Libraries/libserver.dylib

Note: Correct the version number (in jdk1.7.0_79.jdk) path in the above example to make it point to the correct path on your machine.

1. Set java.library.path by adding the following lines at the end of “/Applications/Adobe Flash Builder 4.7/Adobe Flash Builder 4.7.app/Contents/MacOS/Adobe Flash Builder 4.7.ini”.

-Djava.library.path=../../../eclipse/plugins/com.adobe.flexide.nativelibs_4.7.0.349722/os/macosx/:../../../eclipse/plugins/com.adobe.flexide.amt_4.7.0.349722/os/macosx/:../../../eclipse/plugins/com.adobe.flexbuilder.utils.osnative_4.7.0.349722/os/macosx/

Restart your machine and launch Flash Builder.
