'Admin Image' flag set in SummaryInfo stream.

[SujalBirari]

Hi, I am a newbie to the Setup domain and have gotten a pretty much knowledge of making installers using WiX. Now I have been trying to create Patches (.msp) using WiX V4+.
But I get the following error -
ERROR : Error return code from proces : 223. Response from process : wix.exe : error WIX0223: Failed to open database 'Temp\dst\Demo_setup.msi'. Ensure it is a valid database, and it is not open by another process.

I dont know the exact cause for this but I tried to validate my upgrade msi, then I get the following validation warning -
warning WIX1076: ICE39: 'Admin Image' flag set in SummaryInfo stream. Should be set only for Admin packages.

I really need help in this, my question is that -
What changes do we do in our msi wix source file (.wxs) that causes the Admin Image to set in msi.
