I know that MAINTENANCE variable is set to TRUE if there is an uninstall key for an InstallScript project in the registry that points to a valid InstallScript log file on the machine (typically in C:\Program Files\InstallShield Installation Information\{ProductCode}). I am trying to find out where in the installer it sets the value of MAINTENANCE variable. I am creating installer which uninstalls the product if installed already and then should proceed as a first time install. In my case I put the uninstall code in OnSetTargetDir event, which is the first initialization event. But still MAINTENANCE variable is TRUE. I am stuck here please help.
