IceExt 0.51 - With Installer

I'm having a problem getting this to work as well... Installation goes smoothly, but when I try to start the service, I get the following:

System error 1450 has occurred.

Insufficient system resources exist to complete the requested service.

My setup is nothing unusual, WinXPPro+SP1, DS3.0, VS2003. I assure you that there is plenty of memory available; to test, I wrote a quick service of my own that simply allocated a bunch of memory, and it started fine, so I know it's not lack of general resources.

Have you seen this error before, or do you have any ideas about what might be wrong?
