Question

What happens if more than one executable is in a component?

Answer

According to the best practices rules, a component should contain at most one executable, DLL, ocx, or help file. One reason for this rule is because at run time if the user chooses Repair for an installed product, Windows Installer checks for the existence of each installed component's key file. If the key file is missing, Windows Installer reinstalls the missing component. Therefore, if a file that is not the key file of a component is missing, it may not be restored during Repair mode.
