Problem with User Account Control (UAC) and VB6 application under Vista

Hi,

We have some vb6 applications running under Vista. No problems if we desactivate the UAC on all computers except on 1 specific computer wich had strange behaviour. On this computer, in the Windows Explorer, we see a little shield next to the icon of one file (TNBUpdater.exe wich is a vb6 application). If we run this file, we have a warning of the UAC (ex: http://www.gradebook-program.com/ima...ac-warning.gif ). Stange? Because the UAC is desactivate on this computer! No problems with all the others computers of the company.

Some remarks:

-1- If we create a new vb6 project and copy/paste all the code, compile and give a different filename then no problems at all on the computer.
-2- If we do the same as step -1- but we kee the same filename as before (TNBUpdater.exe) then the problem is still present with the UAC warning.
-3- If we rename TNBUpdater.exe with something else (ex: test.exe) then the problem is still present.
-5- If I rename another vb6 executable (witch don't get any problems) and I rename that file, then I have the warning problem (and the little shield beside of the icon of the file)!
-6- If I create a new vb6 projet and copy/paste all the code and give a different name (of TNBUpdater.exe) then no problems at all on the computer. The problem is that I MUST keep the same filename.

I searched for hours with no results. Thank you in advance for your help!
