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.

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.

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