UAC and Runtime Themes

Hi,

My Application Setup (App_Setup.exe) displayed the UAC Shield because it contains the word 'Setup'.
I do not want to elevate the App_Setup.exe.
I came across 'Enable Runtime Themes'and With this set the UAC shield goes off,
and my Setup program is not elevated and my task is accomplished.

Question
Why this behaviour as themes have nothing to do with Security ?
Will the behaviour be consistent across all windows/delphi versions ?

I use Delphi Xe2 currently and soon moving to Xe6. Also tested on WinXP/win7/win8.

Regards
Allan

According to this articles:
uac-five-most-common-install-failure-scenarios-and-workarounds
Understanding and Configuring User Account Control in Windows Vista
... if you set proper manifest into exe (setup exe at least) - then you will not have problems any more.
It is not Delphi related, but exe build old way (not using manifest file).
Use Inno setup and you will not have a problem with that.

...and when ms is in question .... nothing is certain.

I do not want to elevate the App_Setup.exe so I cannot use Manifest. Elevating changes the user, I want my application to run under same user as I work on Outlook.pst. What I want to know is

Theming certainly adds manifest into exe - because manifest switch from old comctl (v5) to newer (v6).

As a result when manifest is in exe - Security check is fine. Again, it is not Delphi related - because MS windows request those. Will be in future some changes....does not depent on Delphi (Embarcadero) but Ms first. Adding manifest to your exe is very simple and one time job - like including this line after you build own manifest: {$R MyMan.RES}

Adding this manifest will trigger theming too.

Thanks for all the assistance. Added AsInvoker in custom manifest instead of requireadministrator and that works fine.
