Hi,

I created a relatively simple Windows Service Application using FPC 2.6.4. The application imports CSV data from a monitored folder and updates product tables in a MS SQL Server database.

The Service Application installed and ran perfectly on my Windows 7 workstation. It also installed and ran perfectly on our Development Server (Windows 2008 R2 SP1 64-bit).

But when we deployed the application to our client's test server (also Windows 2008 R2 SP1 64-bit) we got the following error trying to register the service.

==============================================
C:\Q-Point\csvimporter>csvimporter_service
Usage: C:\Q-Point\csvimporter\csvimporter_service.exe [command] Where command is one of the following:
-i --install To install the program as a service -u --uninstall To uninstall the service
-r --run To run the service

C:\Q-Point\csvimporter>csvimporter_service -i
exception at 0042CD50:
System error, (OS Code 5):
Access is denied.
.

C:\Q-Point\csvimporter>
==============================================

Immediately I thought we don't have enough permissions on the client test server. The client came back and said the user we are using is an Administrator user. So permissions shouldn't be a problem. :-/

Any thoughts on what it could be?

More details on the application:
--------------------------------
The application is based on the daemonapp.pp unit - part of FCL-Extra. I've followed Michael van Canneyts "daemon.pdf" article to the letter. I created the application, created the daemon thread etc. As I mentioned, it works fine on my workstation and on our development test server. But doesn't install on the client's test server.

I Googled the error and came across a FPC-Pascal message from 2011. [http://lists.freepascal.org/pipermail/fpc-pascal/2011-October/030464.html]. But in that discussion the developer tried to query the Windows Services by instantiating a TServiceManager instance. In our case we are using the daemonapp unit instead.

Any help would be greatly appreciated.

Regards,
Graeme

Just a quick follow-up...

I eventually found the problem (by pure luck). Windows Server is weird! Even though we logged in with an Administrator privileged account, when you open the standard Command Prompt window, it is NOT admin privileged. Thus the error. We had to right click the Command Prompt shortcut and select "Run as Administrator" - then the service registered and ran fine.

That's the case since Windows Vista. Maybe you have disabled UAC or any involved mechanisms on the development machines?

Interesting, thanks for mentioning that. I know I've disabled UAC on my work laptop. I'm not in control of our development server, but I'll ask the admin when he is back in the office.

It's one of the reasons why I keep UAC enabled on my Windows systems: I catch such problems immediately ;)

I stopped doing that, because the constant messages are a real PITA.

Michael.

I stopped doing that, because the constant messages are a real PITA.

Our main application requires admin rights as well, but quite quickly my muscle memory has taken over so that I can just dismiss the UAC dialog without thinking much about it. (I did disable the "use secure desktop" option though so that I don't get a black screen for some seconds...)

Hi Michael,

I did notice those (and don't like it either), but unfortunately nothing I can do about it. It is my work address and our mail server injects those "disclaimers" _after_ we sent the messages from our computers.

I'll try and limit posts from my work address to this mailing list.
