I use: AI 14.1.1 enterprise
I want to do this:
1. search for a Registry key
2. if it exists, show a message box with OK and Cancel (in the wizard dialog stage after the searches)
3. When Cancel pressed, exit the installation
Step 1. and 2. are not problem
To show the message box I use the custom action 'Display message box'
But I do not manage to exit the installation when cancel is pressed, as it seems the return value of the message box is ignored.
The message box shall be displayed when the installation is started with the parameter /qr, as well.
Or I can add an additional dialog before the 'license agreement' dialog, but this is not shown when the installation is started with the option /qr
If it is possible to show a step even with /qr I would prefer this.
(I tried to show a message box via a Vbscript and by an attached exe file, but the message box is never shown in 'Wizard Dialog stage', only when I move the according custom action to Install Execution state)
Thank you, Chris
