Hello Edhy,

You can deploy the .Net 4.0 framework within an update to your deployed software using AppLife Update. There are a few things to consider as you plan this.

1. The framework is ~50 MB.  The client without the framework currently installed will need to download this whether the installer is included in your application update, or downloaded as the update is executed.  If your application downloads updates in the background, and your users dont have to wait for that download, you might prefer to include the full framework in your update.  On the other hand, if you suspect most of your clients already have the 4.0 framework, you might prefer to include the web installer, so that the clients that already have it wont need to download it.  And finally, if its possible that your clients wont have web access (internal clients), you'll have to include the full installer with your update.
   
   
2. The framework installer takes time to execute.  If you are using the AppLife Update Windows Service for permissions elevation, you wont be able to show the framework installer progress window.  In this case, it might be better to include the full install in your update, minimizing the amount of time the framework installer needs to run.

Here's how to deploy the .Net 4.0 framework within an update:

1.  Detect whether the 4.0 framework is currently installed, so that the actions that install the update can be conditionally executed.

2.  Include either the full framework install package or the web installer.  This can be placed in the update package directory so that they are removed automatically when the update completes.

3.  Install the .Net Framework if it isnt already installed.  Use the appropriate command line arguments to require user interaction, passively install, or quietly install.  Inspect the exit code to identify whether a reboot is required.  Use this exit code to conditionally execute a Restart Operating System action.  (Because we need to look at this, using a Dynamic Code action to launch the update is preferred.)

4.  Update your host application, just like a normal update.

5. Conditionally restart the operating system.

There is an example aup project file that demonstrates these steps. The dynamic code action includes more info as code comments.
