1) If you run the same msi again you enter the maintenance mode where one can choose: repair, remove, change. 2) If you regenerate again the MSI, by rebuilding it, with the _same_ version but different Product Id (eg when you have in the code: Product Id="*"), and you have in the code smth like: <CustomAction Id="CurrentVersionDetected" Error="2001"/> <InstallExecuteSequence> <Custom Action="CurrentVersionDetected" After="AppSearch">SELFFOUND</Custom> ... </InstallExecuteSequence> <InstallUISequence> <Custom Action="CurrentVersionDetected" After="AppSearch">SELFFOUND</Custom> ... </InstallUISequence> <UI> <Error Id="2001">!(loc.Error2001)</Error> </UI> when you run this second msi you'll get the error saying that it was found and the installer will bail out.
