Problem installing drivers from QtInstaller

[Agurtza]

Hi!!

I am having some problems installing drivers with my application. I use QtInstaller 3.2.2 to do the installer, in windows.

If I install the driver without using the installer it always works perfectly.
But with the installer, it gives me problems, it retries several times and when I click 'Ignore', then it does it correctly. But while I click on 'Retry' it always fails.

The call to that installer is as follows:

Component.prototype.createOperationsForArchive = function(archive)
{
        // add an extract operation with a modified path
	component.addOperation("Extract", archive, "@TargetDir@/VCPdriver");
	if (installer.isInstaller()) 
	{
		component.addElevatedOperation("Execute","{0,256}", "@TargetDir@\\VCPdriver\\CP210xVCPInstaller_x64.exe");
	}
}

And in the package file:

<RequiresAdminRights>true</RequiresAdminRights>

The error code is as follows: -2147418112
There is no error information in the event viewer.

Any ideas?
Thank you!
