    Using a third party installation for an AIR app

    Bill McLean Level 1
      Background:

      We have a compute intensive application that provides services to the our air application. We are want to distribute both using a single installer.

      We have accomplished this by:

      1) On a reference machine we install our air application using the air installer.

      2) We build our third party installer insuring that all the files that the air installed are included as part of the .msi built by the third party installation tool. Of course we include all files to be installed by our compute intensive application.

      We have validated this on a number of target machines and it seems that this process seems to work correctly.

      Questions:

      1) Is it sufficent to just replace the .swf file when code changes occur in the AIR application? It appears to be.

      2) Are there any issues that need to be addressed using this technique?

      3) I

          There are a couple of issues with this approach:

          1) You won't be able to use the encrypted local store or DRM features. Modifying the installed .swf, etc. without re-installing the application breaks the application's signature, and a valid signature is required to access those features.

          2) Installing the same files via two different installers breaks the MSI component model. Among other problems, that means uninstalling either of these two products will cause the shared files to be prematurely uninstalled.

          You might consider instead creating a single installation process for both pieces. You can do this by signing up to redistribute the runtime; when you do so, you'll get instructions helpful for building such combined installers.
