The Adobe Application Manager Enterprise Edition lets IT specialists package Flash Builder 4.5 as an MSI or PKG. Then, they can use the MSI or PKG for silent deployment using industry-standard tools.
To silently install Flash Builder preconfigured with a bundled copy of Eclipse, follow the instructions at http://www.adobe.com/devnet/creativesuite/enterprisedeployment.html
To silently install Flash Builder as a plug-in into a separate Eclipse installation, follow these steps, as applicable to your operating system:
Start the Application Manager, and enter the package information. Specify the package name, the location at which you want to install the package, and the product install folder. For detailed information about using the Application Manager, see Creative Suite 5 Enterprise Deployment Guide.
Create a link file to link Flash Builder with your Eclipse installation. You can generate the link file using the Plug-in Utility installer, as follows:
Go to the Eclipse installation folder and copy the .eclipseproduct file. Then, go to the Eclipse folder within the Flash Builder installation and paste the .eclipseproduct file that you copied. After that, rename the .eclipseproduct file in the Flash Builder installation folder to .eclipseextension.
