Windows Service, how can I uninstall from VS Setup project?

Question

Hi There,

I have created a windows service, it works great, but as soon as I try to install the service, it removed the directory, however, the service did not get removed, and when I try to install the service again, it give me an error 1001: Service already exists. How can I fix that?

And also, is there any code for me to remove the service when I uninstall the project?

Thanks

Answer 1

You might need to remove it from the registry at [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services]

Answer 2

Have a look at this post. It references another one, so, between them, they may have your solution.

Answer 3

You can use installutil.exe to install or uninstall a service from the command line.

To install: installutil yourproject.exe

To uninstall: installutil /u yourproject.exe

You can also use sc delete from the command line. Type sc by itself to get the list of parameters.

Lastly you can use the ServiceInstaller.Uninstall() method if you're using the predefined installation component. You'll have to call it from the Uninstall handler of your installer.
