QtService: Start installed Service on Windows10

I have created a simple service application for testing with QtService. This can be easily executed in the QtCreator using the command line arguments: -exec: This allows me to debug the service in QtCreator -install: This allows the service to be installed (Alternatively, I can also install the service via cmd with the sc command).

After I have installed the service, I try to start it in the Windows service management. However, the error message appears: The service "MyService" on "Local computer" could not be started. Error 1053: The service did not respond to the start or control request in time.

This error message appears immediately without trying to start the service for 30 seconds. I tried debug and release mode.

My guess is that Qt dlls must also be next to the EXE. But I don't know which.

on win10,if you want it to work as service ,you should install it in powershell in admin mode, or it would not work! screenshort work well in admin mode screenshort not work well in normal mode

I found a solution:

  1. In Qt 5.13.1(MinGW 7.3.0 64-bit) Compiler (In my case) change the directory to exe file. Then enter following command: windeployqt.exe .

  2. Put the QtSolutions_service-head.dll next to exe file.

Now I can start the service.
