[Bug]: CKAN First time URLHandlersPrompt fails due to running as root protection

[Lewis98]

Is there an existing issue for this?

• I have searched the existing issues

Operating System

Windows 10 Home V22H2 (OS Build 19045.4651)

CKAN Version

v1.34.4

Games

KSP 1

Game Version

1.12.5.3190

Did you make any manual changes to your game folder (i.e., not via CKAN)?

None, Fresh KSP Install, should be unrelated

Describe the bug

Received the following prompt on first time launching CKAN:

Responding yes provides the following command prompt warning:

The action attempted by the CKAN launcher appears to be unsuccessful.

Steps to reproduce

Pre-requisite: Machine with no prior installation or usage of CKAN

1. Download CKAN executable

2. Run CKAN

3. Respond yes to the following prompt:
   

4. Warning is displayed on command prompt

Relevant log output

Couldn't find any relevant log output

Checked \CKAN\GUI\URLHandlers.cs lines 69-80 and there seems to be a workaround for this issue already implemented, not entirely sure what's causing it to fail

Running ckan.exe manually as administrator with the '--asroot' flag appears to function fine, without warning, and resolves the issue on future launches (without admin perms).

CKAN/GUI/URLHandlers.cs

Lines 69 to 80 in 701afa1

	if (user.RaiseYesNoDialog(Properties.Resources.URLHandlersPrompt))
	{
	// we need elevation to write to the registry
	Process.Start(new ProcessStartInfo(Assembly.GetEntryAssembly().Location)
	{
	// trigger a UAC prompt (if UAC is enabled)
	Verb = "runas",
	// .NET ignores Verb without this
	UseShellExecute = true,
	Arguments = $"gui --asroot {UrlRegistrationArgument}"
	});
	}

Hi @Lewis98, thanks for the report. You're right, this was already fixed in #3996, but there hasn't been a major release since then. If you like, you can try the dev build to see the fix in action:
