Error during Uninstallation and installation Process

[user2301]

I am trying to install windows service application via qt installer. The install is working only if the windows service is not already installed and not already running in the system – otherwise I will get the error from within the QT installer. when I uninstall the windows service just by removing my windows service TargetDir directory but without stopping and removing my windows service from the list of windows services. How to execute the stop and remove commands when uninstalling my windows service from the QT installer? Is there anything similar to installscript.qs such as uninstallscript.qs to stop and remove the windows service?

I tried with below installscript.qs but did not work.

function Component()
{   
}

Component.prototype.createOperations = function()
{
	component.createOperations();
    if (systemInfo.productType === "windows") {
		if (component.isInstalled() || component.uninstallationRequested()) {
	   component.addElevatedOperation("Execute", "@TargetDir@/platform/tools/Server/TestServer.exe", "stop");	
	   component.addElevatedOperation("Execute", "@TargetDir@/platform/tools/Server/TestServer.exe", "remove");	
	   }
	   component.addElevatedOperation("Execute", "@TargetDir@/platform/tools/Server/TestServer.exe", "install");
	   component.addElevatedOperation("Execute", "@TargetDir@/platform/tools/Server/TestServer.exe", "start");
    }
}

U can choose different target path for installation (Just for testing).
QTIFW does for already installed path https://bugreports.qt.io/browse/QTIFW-482

otherwise I will get the error from within the QT installer.

What error you are getting??

I uninstall the windows service just by removing my windows service TargetDir directory

You should use MaintenanceTool.exe for clean uninstall . Its present in target directory of your installed application.
