Applications must be run with administrator privileges. How to ask the user is? How to verify that he agreed to? How do I know whether already running application as an administrator?

Made as described here by the user ChrisW67. The result is not received. If possible, give an example of "Hello world" project.

P.S Windows 7. Am writing in Qt Creator. Qt5.2

Disclaimer: Why does your application require admin rights? A modern application should in most cases be able to avoid this. One could use a service for the elevated actions.

I realize that you are using Qt. I don't have access to this tool at the moment, but here are a few general options. Essentially you need to modify the manifest that gets embedded into the binary on compilation:

.NET: How do I force my .NET application to run as administrator? (as stated above; you modify the manifest that gets embedded in your application executable). More here.

<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

Remember to verify admin rights in case the UAC is disabled - in that case the user is not prompted for admin rights on application launch.

C++: In C++ you can set a flag in the project properties: How to run application with Admin privileges using Manifest file in Visual Studio 2005?

Shortcut: You can set up the launching shortcut to require admin rights. The user will then be prompted on launch. "Run this program as an Administrator".

  • I cannot adjust shortcut on launch. Because applications can not be run through the shortcut. Applications are very specific and cross-platform. On Linux, I can install a s bit (chown root a.out; chmod +s a.out) How can I do it on windows? – tioo May 08 '14 at 18:35
  • Is this a small binary doing something simple with a log file output? If you launch such a tool directly from the users "My Documents" folder you should be able to write an output file there. – Stein Åsmul May 08 '14 at 23:54
