Question : Vista says "The requested operation requires elevation" - but this is not true!

I've written a simple test application in C++ that displays a message box. When I want to run this application as standard user on Vista the message "The requested operation requires elevation" is displayed. Running any other application in the same directory works fine.

How can I tell Vista that this application does not require administrator privileges? I unchecked the "Run as administrator" box, but Vista still ask for elevation. And why does Vista block this exe but not the other exe next to it?

Answer : Vista says "The requested operation requires elevation" - but this is not true!

By default the administrator and guest account are disabled for security reasons.
re-reading your comments/
Disabling UAC or working as administrator is no option for me, since the software will run on our customers PCs in critical environments.<< will these customers all be using Vista business?
Otherwise I'm not sure this is possible.
you may need to create a global group policy for it.
 
To open the computer management
Click on Start open Control Panel.
Click on the System and Maintenance link.
If you're viewing the Classic View  you won't see this link.
Simply double-click on the Administrative Tools icon.
In the System and Maintenance window, click on the Administrative Tools link near the bottom of the window.
In the Administrative Tools window, double-click on the Computer Management icon.

If your interested the run cmd> gpedit.msc in xp
it's now secpol.msc but only available in Vista Business and Ultimate I believe not in Vista Home.
as a ref use this to access the Group Policy Object Editor for the Local Computer Policy.
