.net 1.1 EXE in startup folder on VISTA

Our application installs a .NET 1.1 EXE created with VB.NET into the startup
folder on the PC. This works perfectly on Win98SE and XP. If the User
Access Control is OFF on Vista, it also works perfectly there. However, if
the UAC is on, the program is BLOCKED.

I tried to build a manifest file....

<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<asmv3:trustInfo xmlns:asmv3="urn:schemas-microsoft-com:asm.v3">
<asmv3:security>
<asmv3:requestedPrivileges>
<asmv3:requestedExecutionLevel level="asInvoker" uiAccess="true" />
</asmv3:requestedPrivileges>
</asmv3:security>
</asmv3:trustInfo>
</assembly>

It didn't help.

Any way to get this program to launch even if the UAC is turned on? Users
can launch it by right clicking and allowing it to run, but how can it run
normally, like it does on XP, Win98 or Vista when the UAC is off?
