QtIFW Always create registry entry - qt

Question

I'm currently using the Qt-Installer-Framework to create a setup for my application. Everything works fine for now except one thing:
If I install it to any location but C:\Program Files\MyApp, the installer won't create the registry entry for Programs and Features!
Is there a way to tell the installer to always do this?
Edit:
After trying out vairous different combinations, I do know now where the problem comes from:
If I try to install as current user only (set the AllUsers variable to false), it will always work and create an entry in HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{GUID}.
If I install for all users, however, it will try to create a key in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{GUID}. This will only work, if the installer has to elevate it's operations during installation (because I chose a directory I need admin rights for).
So, the error is: The installer won't elevate itself to create the "global" registry entry and thus fails to create it. Any ideas on how to fix it?

Answer 1

Here the link which has answer to this question.
Add the following line to your component's package xml file:
#<RequiresAdminRights>true</RequiresAdminRights>#
And use this line in your script file:
#component.addElevatedOperation("Execute", "someCommand");#
instead of
#component.addOperation("Execute", "someCommand");#

There is boolean installer.gainAdminRights() to gain elevated privileges during runtime but you will have to add it to an installer script (in packages meta directory) something alike
function Component()
{
if (!installer.isInstaller())
{
if (allUsers && installer.gainAdminRights())
{
//Set registry global
} else {
//Set registry local
}
}
}
