64 bit Flex based Desktop application

How to create a 64 bit desktop application using Flash builder and Flex SDK ?

[amritag9336052]

Hi,

Please refer Combined Windows 32-bit and 64-bit AIR SDK on Release Notes Flash Player 29 AIR 29 . For mac osx all applications are 64-bit by default.

Thanks!

Hi,

I have updated AIR_WIN_ARCH value to 64 but even after that the flash builder is able to create 64 bit application on action script project only.

We however have a Flex project. When I export the flex project it is always created as a 32 bit application.

Can I somehow export a Flex project as a 64 bit application ?

[yashy2823074]

Can someone please respond to this ?

Please confirm if this is not feasible. We need to take a decision on the applications fate.

I haven't had issues generating a 64-bit Flex application from Flash Builder. There are a few requirements like opting for captive runtime, setting the aforementioned environment variable and using the right SDK version (29+).

So it is definitely possible and not that hard. You're probably missing something simple.

Hi, I follow really simple steps as mentioned below:

Updated environment variable.

New -> Action Script project -> Project will use AIR SDK 31 -> Finish -> Right click Export -> Release build -> Signed application with Captive runtime -> Finish -> Creates a 64 bit setup

New -> Flex project -> Select Desktop & use default SDK(currently Flex 4.6.0) -> Finish -> Right click Export -> Release build -> Signed application with Captive runtime -> Finish -> Creates a 32 bit setup

I want to build a 64 bit setup with second case that is on creating new Flex project. What is it I am missing here ? Please help.Attached images for reference

Hi mingtianjian​, I have the AIR_WIN_ARCH set to 64 please see below screen. Still the flex project is packaged only as 32 bit.

step2:

<architecture>64</architecture>

step3:

download the demo application

Hi mingtianjian​

Adding <architecture>64</architecture> to flex project gives below error on exporting:

I use Flex Builder 4.7,    AIR30.0

[yashy2823074]

Hi

The Flash builder is 4.6 and AIR 31.0

Do we need to have Flash builder 4.7 ?

[mingtianjian]

you  try Flash builder 4.7

see the Authoring Guidelines in the Adobe AIR release notes
Release Notes Flash Player 31 AIR 31

eg.

Add "-swf-version=42" to the 'Additional compiler arguments' field.

it will work with any SDK, either Adobe Flex SDK, Apache Flex SDK, Adobe AIR SDK, etc.

you can also check the loaderInfo.swfVersion to be sure the correct SWF version is used

I guess the problem is your SDK version. You said you're using Flex 4.6.0. This version does not support 64-bit targeting.

Get the latest Apache Flex from http://flex.apache.org/installer.html

That should do the trick.

Thanks gfantiniAqua​ the application is a 64 bit when I used updated apache SDK

Was this Flex?
I'm really struggling to get a 64-bit flex .apk package from Flash builder.

I've done all the above...
