Windows Agent reinstall issue

Hello
I have a problem with agent on Windows
The very first time I deleted it, I received the error "Error: Yaml:Line 6: Didn't Find Expected Key". I didn’t bother to figure it out and decided to delete everything according to the guide to which I was given a link in the cmd (stop services and delete the entire folder)
When trying to install the new agent, the error "Elastic Agent installed but currently broken: service exist but installation path is missing" appears, then "Failed to install service: Service Elastic Agent Already Exists".
sc stop, sc delete commands stops service but do not delete it
I also cannot reboot the machine because this is a production environment
I don’t delete service through the registry because a reboot is still will be needed
I also tried the --force commands on install and uninstall, but without success.
How can I remove the service or force the agent to reinstall?
