You need to put this on the window open event rather than the client start.

The event object is only available for object events, ie button, window startup etc… not client startup scripts.

Alternatively you could have it set a client tag and read that client tag on your startup screen.

Hi

Thanks for your help.

I put this in the script of my window and works.

if u’Administrator’ in system.security.getRoles():  
value = 1  
else:  
value = 0  
system.gui.getParentWindow(event).getComponentForPath(‘Root Container.BUsuarios’).visible = value

The better option would be to use an expression binding on the visible property and use the expression `hasRole('Administrator') `  
Using a one-shot script for something like has its downsides

Yes.

If you ever implement a feature to switch to a different user, this script will not be triggered, and the previous access rights will remain.

It's way better to use the included security features in Ignition (by right-clicking on a component, and selecting the security options).

yes is better user "Security options " in the component and more easy.
