Click menu item display message if file not available

Scenario:

I have an updater application that I want to add to my current project as a separate application. When the user opens the main application and clicks on check for updates I want a message to be displayed saying something like "The current module is not installed". However, if the user is sent an installer that installs the updater into the main application, the next time the user clicks on check for updates, the updater is run.

Is this possible?

Thank you

Yes it is possible. It's called an If statement.

Thank you. I will Google If Statement.

Surely you would have to deploy a new version of your app to add the update feature to begin with anyway, so why wouldn't you just include the updater with that new version?
