QtIFW: Mkdir and Delte does not work at C:

Schenk

Hi,

i want to install my application under C:\Program Files\myapp. The follwing code will create the directory "webservices" automatically.

Component.prototype.createOperationsForArchive = function(archive) {	
	component.addOperation("Extract", archive, "@TargetDir@/webservices");
}

But if i want to create and delete a folder like this:

var dir = installer.value("TargetDir");	
	component.addElevatedOperation("Delete", dir + "/webservices");

or use the installer

if(installer.isInstaller()){		
		if(installer.fileExists(dir +"/tmp") == true){			
			installer.performOperation("Delete", "@TargetDir@/tmp");					
		}	
	}

it will not work.

If i use another installation directory like C:\Users it will work witouht Problems.

How can i create and delete files under C:?

best regard and thank you for your help in advance

You need administrator permissions to modify C:/ on modern Windowses.

addElevatedOperation

I thought addElevatedOperation gaisn Admin rights?

I don't know. Do you see the popup asking you to grant admin rights when you run your installer?

Schenk

Yes, i see it, but it does not work.

I could get AdminRights on the config script with installer.gainAdminRights() and then work with performOperation(). This works.

But if i want to delete or move files after installation in the package scripts, it will not work.

Function registered:

installer.installationFinished.connect(this, Component.prototype.deleteTempFiles);

Later:

Component.prototype.deleteTempFiles = function(){
	var dir = installer.value("TargetDir");	
	QMessageBox.information("asasas", "asasa", "dir: " + dir, QMessageBox.Ok);
	installer.gainAdminRights();	
	
	//component.addElevatedOperation("Delete", dir + "temp.txt");
	installer.performOperation("Delete", dir + "temp.txt");
	
	installer.dropAdminRights();
}

Neither component.addElevatedOperation() nor installer.performOperation in combination with gain and dropAdminRights() will not work in package script under C:\Program Files.

Ok, i found the solution:

installer.performOperation("Delete", dir + "/temp.txt"); // the slash was missing

Only this one will work

Component.prototype.deleteTempFiles = function(){
	var dir = installer.value("TargetDir");	
	installer.gainAdminRights();		
	//component.addElevatedOperation("Delete", dir + "/temp.txt");
	installer.performOperation("Delete", dir + "/temp.txt");	
	installer.dropAdminRights();
}

Try to do an elevated Operation will not work! You have to use the installer-solution.

Schenk

Curiously, this operation works...

Component.prototype.createOperations = function()
{
    component.createOperations();		
   component.addElevatedOperation("Execute", "@TargetDir@/foo.exe");	
}
