how to get 'Run as administrator' in jar applications

Question

I have a desktop java application that uses Swing as a GUI library. There is an installer that I have to install inside this application, but it must have administrative privileges.

I am using

Process p = Runtime.getRuntime().exec(pathToTheExeInstaller);

to install the program. But it has this error when running it without administrator privilege:

Is there a way to get Run as administrator in the context menu (the right click menu) in the generated jar file when clean and build is used in NetBeans:

Try running cmd as administrator and starting your jar from there maybe. — FThompson, Aug 05 '18 at 08:02
This will work, but as a client I don't want him to run cmd as administrator, I want him to simply just click a button. — Tarek, Aug 05 '18 at 08:03

This is what you need,

Runtime.getRuntime().exec("powershell.exe Start-Process 'pathToTheExeInstaller' -verb RunAs");

This will give a prompt to the user asking permissions to get elevated access for your installer.

Example

Runtime.getRuntime().exec("powershell.exe Start-Process 'notepad.exe' -verb RunAs");

I tried this, it gives an error with the arguments, the path contains spaces, so I put "", still gives an error. – Tarek Aug 05 '18 at 09:16
I did, but the problem is that the path has `~1` in it, it what `createTempDirectory` returns. – Tarek Aug 05 '18 at 09:28
I'm getting this error: `Start-Process : This command cannot be run due to the error: The system cannot find the file specified. At line:1 char:1 + Start-Process C:\Users\TAREQK~1\AppData\Local\Temp\NSIS Installer7238 ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidOperation: (:) [Start-Process], InvalidOperationException + FullyQualifiedErrorId : InvalidOperationException,Microsoft.PowerShell.Commands.StartProcessCommand` – Tarek Aug 05 '18 at 09:28
@Tarek I've edited the answer, check it now. Use `'` instead of `"`. – Roshana Pitigala Aug 05 '18 at 09:29
yeah sorry I forgot. – Tarek Aug 05 '18 at 11:33
I assume this only work on windows, is there a solution that works on any platform ? – BHA Bilel Jun 08 '21 at 02:01

Right-click on the "command prompt" and choose "run as administrator", then you can

java -jar myprogram.jar
