Hi Martin,

These are highly particular requirements for your application. You can only achieve this by programming your own custom action which detects these settings and displays the proper message before erroring out. MSDN should list some API to call to find out these settings you require.

I hope this helps.

Hi,

I want to prevent the installation (perequisites, etc) with these conditions.

1) How I can prevent the perequisites installatino with a custom IntallerClass ?
2) How I can display a message to the user ?
3) How I can stop the installation process ?

Best regards,

Martin

Hi Martin,

You can try the following:
- create a custom action that does your search for the appropriate settings and sets a property depending on whether it succeeded or not. Place the custom action under Begin standard action both in the InstallUISequence and InstallExecuteSequence. Hold Shift and drag the custom action between the two sequences to make it a shared custom action.
- create a launch condition that is conditioned using the property created in the previous step
- make sure your prerequisites are feature-based.

I hope this helps.

Best regards,
Gabriel

  [RunInstaller( true )]
  public partial class Utilities : System.Configuration.Install.Installer
  {
    public Utilities( )
    {
      InitializeComponent( );
    }

    protected override void OnBeforeInstall( IDictionary savedState )
    {
      base.OnBeforeInstall( savedState );
      /*
      StreamWriter newWriter = File.CreateText( "C:\\test\\bonjour.txt" );

      newWriter.Write( "Bonjour les amis !!!" );

      newWriter.Close( );
      */
    }
  }
}

Hello,

Are you using the ".Net Installer Class Action" predefined custom action to run your Installer Class?

Hi Martin,

It appears you are overriding the OnBeforeInstall method, however in your custom action you are setting the action to "Install".
It is advisable in your code you override the Install method and execute your code there instead of OnBeforeInstall.
