[news.eclipse.platform.rcp] Re: Verification of install

Absolutely,

I do thing like this in my WorkbenchWindowAdvisor.preWindowOpen() 
method.  I check for catastrophic errors at this point - lack of 
expected connected devices, database errors, etc, and if there are 
errors, issue an error dialog and then exit:

    public void preWindowOpen() {
    	if (some catastrophic error) {
    		MessageDialog.openError (getWindowConfigurer()
				.getWindow().getShell(),
    			"Invalid system configuration",
    			"Blah, Blah, Blah");
    		PlatformUI.getWorkbench().close();
    	}

I also do more non-catastrophic checks in my 
WorkbenchWindowAdvisor.postWindowOpen() class.  By this time the main 
workbench window is up and the messages displayed are just warnings
