Upgrading Windows service using Inno Setup
I've created a basic Windows service installation using Inno Setup. both install and uninstall works properly.
However, I'm having issues with the upgrade procedure.
In order to upgrade the service executable it is necessary to stop the service, and only after the service is completely stopped can the updated executables be placed in the target folder.
How can I execute a service-stop command and wait for the service to be completely stopped before the file deployment step is initiated?
Answer
The code below comes from the following page:
http://www.vincenzo.net/isxkb/index.php?title=Service_-_Functions_to_Start%2C_Stop%2C_Install%2C_Remove_a_Service
However, I had to apply a minor fix to make it work.
Note that I originally posted this answer in 2010. The code at the page above was updated in 2011, so it might be worth a visit.
I use this code in my installer, as an #include. It is compiled in Inno Setup ANSI.
It may work for the Unicode version of Inno Setup by replacing A@ with W@ in all external declarations (thank you JeroenWiertPluimers for pointing that out).
Also note that the StartService and StopService just send a start/stop signal, but do not wait for the service to be in the running of stopped state. You can construct code that would wait for the service to be running, using the using IsServiceRunning in conjunction with the Pascal Script Sleep() function. Or just Sleep() a predefined number of seconds.
The code implements these functions:
function IsServiceInstalled(ServiceName: string) : boolean;
function IsServiceRunning(ServiceName: string) : boolean;
function InstallService(FileName, ServiceName, DisplayName, Description : string;ServiceType,StartType :cardinal) : boolean;
function RemoveService(ServiceName: string) : boolean;
function StartService(ServiceName: string) : boolean;
function StopService(ServiceName: string) : boolean;
function SetupService(service, port, comment: string) : boolean;
The actual code:

dwCurrentState : cardinal;
dwControlsAccepted : cardinal;
dwWin32ExitCode : cardinal;
dwServiceSpecificExitCode : cardinal;
dwCheckPoint : cardinal;
