Unable to get Detect / Exit Conditions to work for Packages I just cannot figure out how to achieve following: Only install my package (exe) when it's not installed already Abort setup when package execution fails Seems to be pretty basic and exactly what Detection / Abort Conditions seem to exist for. So what I do is following: Create Registry key xyz in myPackage.exe if it succeeded, otherwise skip creating registry xyz and use that for the Detect Conditon and configure Prompting for ExitCondition. <Exe>
