I Created installation setup using Install shield 2014 - Basic MSI project. After installing my exe, manually I removed some(dll) files in installation path. Then Repair using exe. If you see in control panel(Programs and Features) the size is increased (compared with Initial size). Is this excepted behavior ? If yes, let us know the reason behind this. If No, Please guide us to resolve this issue.

Ex : First time installation size was showing 20 MB in control panel and manually I removed some(dll) files in installation path and then performed "Repair" through setup. Then the Size was increased to 30 MB.
