How to allocate Administrator permission to Standard User for Windows

We have an application(Myapp.exe), which is runs under administrator account properly( as it edit/update/write DLL in registry). But due to to security resons we dont want to provide Admin password to all users, and we want to run application under Standard User ( member of Users group only).
I did these setting in MyApp.exe.manifest
<requestedExecutionLevel level="asInvoker" uiAccess="false" />
and linked in the file MyApp.rc as given below
Partial Class MyApp :Form
{
Public MyApp
{
InitializeComponent();
---
---
---
#define MANIFEST_RESOURCE_ID 1
MANIFEST_RESOURCE_ID RT_MANIFEST "ProLaw.exe.manifest"
}
}
I buld the project, and through Standard user i tried to run the project, but it is still asking Administrator password.
Am i missing any step?
