You can programmatically set the "Run this program as an administrator" flag (the option you find in the Compatibility tab of an EXE's properties), by setting a simple registry key. You need to create a string value (REG_SZ) under one of these keys (if you want the setting to be per user or per machine, respectively):

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

or

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

The name of the value needs to be the full path to your executable (if the path contains spaces, do not surround the path with quotes) and the data of the value must contain the string RUNASADMIN.

For sample:

reg.exe Add "HKLM\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers" /v "C:\Program Files\MyApp\Test.exe" /d "PUT__VALUE__HERE"
