Hello,
I have configured my custom "Prerequisite" Dialog page so that the Next button has two control conditions:
When PROCEED_INSTALLATION is set to "false," the action is disabled.
When PROCEED_INSTALLATION is set to "true," the action is enabled.
I possess a custom property known as PROCEED_INSTALLATION. Initially, the condition (PROCEED_INSTALLATION) is set to FALSE before the Dialog is displayed, resulting in the Next button being displayed as disabled.
Upon clicking a button, a Custom Action is triggered, which calls a function in a Dynamic Link Library (DLL). This function, in turn, sets the aforementioned condition to "TRUE."
Regrettably, even after the function has returned, the Next button remains disabled. I would greatly appreciate your assistance in resolving this issue.
