How to set “Run this program as an administrator” programmatically

Question

I\'m having a problem with good ol\' bdeadmin.exe in Vista. First, let\'s get the predictable responses out of the way:

\"You should not require your application to

Answer 1

Use a wrap program which uses ShellExcute that uses "runas" as its "verb" to run the program you want.

Answer 2

Pack your app into WinRar SFX with silent mode + admin request mode.

Much simpler than messing with .MSI variables.

Answer 3

This is a long shot, but if you have the word "setup" or "install" in the name of the EXE, Windows will prompt for elevation when running it. I don't know if that'll work with a control panel applet, though.

Answer 4

I'd be surprised if this was possible. It would be an ideal way for malicious code to abuse the system. You're probably going to have tell the user the administrator must install or they must have admin rights (like all the other programs on windows do).

Answer 5

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"

Answer 6

Have you tried Microsoft's Application Compatibility Toolkit? It analyses your app and provides compatibility shims that might be able to help resolve your problem.
