Windows Service Install Ends in Rollback

It turns out that the install might, or probably will, fail if that service is highlighted in the Services applet. It's safest to just close the Services applet, install the service, and then re-open the Services applet. It's really stupid.

Also, make sure to run the console as admin.

I experienced the same and the issue for me was that a service with the same name was already installed. So in order to install the new service I had to uninstall the older services. I am learning how to create and setup windows services and thus the naming conflicting. Tried uninstalling the service first through:

c:\Windows\Microsoft.NET\Framework64\v4.0.30319\installutil -u servicename.exe

Once this statement executes successfully, install your service and it should succeed without any rollbacks.

Right Click on Command Prompt and choose RUN AS ADMINISTRATOR
Then copy and paste in: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\InstallUtil.exe C:\TestService\bin\Debug\TestService.exe

Result in TestService.InstallLog is:

Installing service TestService...
Service TestService has been successfully installed.
