Install a Windows service using a Windows command prompt?

Nothing wrong with SC Create command. Just you need to know the correct args :

SC CREATE "MySVC" binpath= "D:\Me\Services\MySVC\MySVC.exe"

Navigate to the installutil.exe in your .net folder (for .net 4 it's C:\Windows\Microsoft.NET\Framework\v4.0.30319 for example) and use it to install your service, like this:

"C:\Windows\Microsoft.NET\Framework\v4.0.30319\installutil.exe" "c:\myservice.exe"

Regarding a comment, for 64bit apps, use below:

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\installutil.exe
