After you compile your application into a SWF file, you write a wrapper that embeds that SWF file. Clients request this wrapper directly. You can use Adobe Flex Builder to automatically generate a wrapper, or you can write one yourself. Express Install is included by default in the wrappers generated by Flex Builder.

Disable Express Install in Flex Builder

1. Open your project in Flex Builder.
2. Select Project > Properties.
3. Select Flex Compiler from the tree at the left.
4. Deselect the Use Express Install option.
5. Click OK to save your changes.

The wrapper generated by the Flex module for Apache and IIS does not support Express Install.

If you write your own wrapper, however, you must add Express Install manually. Sample wrapper templates are available in the sdk_install_dir/templates directory for Flex SDK and the install_dir/sdks/3.0.0/templates directory for Flex Builder. For more information, see About the HTML templates.

Refer to the following steps if you write your own wrapper and add Express Install support to it, and customize a generated wrapper or template. For more information about creating a wrapper, see Creating a Wrapper.
