On my custom "Validate Licence" Dialog page I have set the Next button to have two Control Conditions ...
The condition (MCLICENCEVALIDATED) is set to FALSE prior to the Dialog being displayed and the Next button is displayed as disabled accordingly.
The Validate Licence button also seen in the above image, when clicked executes a Custom Action that calls a function in a DLL which in turn sets the said condition to "TRUE".
Unfortunately, after the Validate Licence function has returned, the Next button is not enabled.
I have also created a Custom Action to refresh the current dialog after calling the Validate Licence function however the Next button remains disabled.
How do I enable the Next button?
