I have added a condition INSTALLDIR <> WindowsVolume to the "Next" button of the InstallDir dialog to prevent installation to the windows root drive.
This condition gets validated and next button gets disabled if the condition is true when the user clicks the button.
But if the user enters the windows root folder and press enter, it directly navigates the user to the ready to install screen without validating the condition

I have read somewhere that the property gets validated only on a control click event. But how do I handle this situation?? when i proceed with the installation, everything gets installed on the root drive.

Any ideas??

Properties like WindowsVolume end with a \ and I&#039;d guess that the user input doesn&#039;t.
