Qt IFW silentUpdate fails in Windows when the application is running

Qt IFW silentUpdate fails in Windows 7 when the application is already running with the error

Unable to update components. Please stop these processes..

Updating from GUI of the maintenancetool will be successful even when the application is running.

Apparently the silentUpdate mode misses something that the GUI mode has.

Hi,

What version of QtIFW are you using ?

Can you provide a minimal compilable example that shows the behaviour ?

IFW Version Info

IFW Version: 3.0.1, built with Qt 5.9.0.
Build date: Sep 14 2017
Installer Framework SHA1: a1f5686

The problem is reproducible in every way possible.

I have uploaded the sample which can be downloaded from https://files.fm/u/wqrrppkk

Steps to reproduce the bug

Create an online only installer
Create the repository (of packages) accessible from localhost
Install
Run the installed app.exe and leave it running. The titlebar will display "Version 1"
Create the repository (of packages_update) accessible from localhost
When app.exe is running, run maintainancetool -v --silentUpdate

Result

Unable to update components. Please stop these processes.. <path>/app.exe

Proper Working from the GUI mode

Do all the above steps except running the maintainancetool -v --silentUpdate
Instead run the maintainancetool.exe manually by double clicking from the Explorer
Install the updates when app.exe is already running.

Result
The update is successful even when app.exe is running without affecting it ( like in linux). Newer instances of app.exe will run the newly installed update showing "Version 2" in the title-bar. This is the intended result.

Somehow the "maintainancetool -v --silentUpdate" fails to deliver what the GUI mode delivers.
