I've got a custom LaunchFileOrURL action that is executing at the end of my installer process during the "Finish Dialogs Stage". It is invoking an existing uninst.exe in a specified directory on the target computer (existing from a previous iteration of the software). I'd like to be able to only execute this if the referenced directory exists. Furthermore, I'd like to give the user a dialog box or popup to confirm whether they indeed want to execute this uninst.exe on their machine before proceeding. I found some information after browsing the help pages on: http://www.advancedinstaller.com/user-g ... l-msi.html, where it references one of the things I mentioned above (the user prompt), but I'm not sure how to implement this.
Any help with either or both of these features would be greatly appreciated!! Thanks!
