Problems with NSClient++ on XP SP3

I am having a problem getting the NSClient++ running on a workstation that is running XP Pro SP3. The previous version of NSClient 0.3.5 would just crash, so I downloaded 0.3.6-RC6 and it runs, but I cannot file or open the “services manager” that it tells you to do in the documentation. Anyone have any idea what I should do, the system process starts along with the SysTray, but I only get the two plus taskbar icons.

Any help would be great, thank you.
