I'm using iexpress to create deploy able executable. In this package It does nothing but extracts two files (.msi and .exe) in a temp folder and run the .exe file from temp. then the installation process proceed as with two files. i.e. setup wizard starts and installs the product on the machine as needed. But after completing the installation it also deletes the fiels from temp folder which causes later product can't be repaired and asks the user to browse the .msi file that is not there. So I wants to enforce the screen in the installation that must ask the user whether that wants to repair the product later. if yes then it should keep these two files in temp folder else delete as now happening.

Please anybody help me how I can add a new screen in the setup wizard to confirm future repair need and how I can keep the installation files in the temp folder if repair required.

Please help me its urgent.
