you must change in your dpr source the property ServiceName of the method ROStartService.
begin
if ROStartService('ServiceName', 'DisplayName', 'Description');
begin
ROService.CreateForm(TServerDataModule, ServerDataModule);
ROService.Run;
Exit;
end;
end;
Strange thing happened, I already tried that but it didn’t work, I said that in my question, but I tried it again after your answer and it worked fine, seems I didn’t make a build for the project :-/.
