Hello,

I am using Firebird-3.0.3.32900_0_Win32.exe on XP when I try to start service in installed FB folder with C:\Firebird\Firebird_3_0>instsvc sta or instsvc sto
I get that message

 "Error occured during OpenService"
The specified service doens't exists as installed service (sorry I had to translate from french)
Usually I start service from .bat file with net start "Firebird Server - firebird3"

Where is the problem please ?
