[wix-users] Msi package update require administrator priviledges when installation didn't.

[Hoover, Jacob]

What happens if you add ALLUSERS="" to the command line?  Do you have any CA's modifying the ALLUSERS property?

Hi,



I installed msi package for single user in C:\Users\user_name\AppData\Local\Apps. Installation didn't require elevated privileges, but when I want update this package using command:



MSIExec /fvamus xxx.msi REINSTALL=ALL /l*xv runmsi.log



the UAC prompt appears.



Update log contains information that elevation is not required:



MSI (s) (C4:F0) [07:44:31:503]: Determined that existing product (either this product or the product being upgraded with a patch) is a dual mode package installed in per-user mode.

[...]

MSI (s) (C4:F0) [07:44:31:504]: MSI_LUA: Package is a dual mode package and is being installed in Per-User mode. No elevation is required.

[...]

MSI (s) (C4:F0) [07:44:32:072]: MSI_LUA: Entering Credential Request. hwnd = 1376978, MsiAction = 3, productname = X, version = 5.1.0.0201, language = 1045, manufacturer = X MSI (s) (C4:F0) [07:44:32:072]: MSI_LUA: (continued)... packagepath = C:\WINDOWS\Installer\1ac6cc.msi, packagesource = C:\Users\xxx\Temp\xxx_update\xxx.msi, dwUpdates = 0 MSI (s) (C4:F0) [07:44:33:242]: MSI_LUA: Credential Request return = 0x800704C7



Installed package and updated package are signed with same, correct certificate. I think the problem appears after install Windows 10 Anniversary Update.



I can provide a msi package if it will be required.

Additional info:

-WiX version: 3.10.3.3007

-.NET version: 4.6.01586

-OS version: Windows 10 Pro version: 1607 build: 14393.693 with UAC turn on
