NCover with Windows Services

Hi, I'm trying to run NCover with a windows service, but i get the following error:

Waiting for profiled application to connect...Connected
Profiled process terminated. Profiler connection not established.

*** Aborted by user.

NCover version is 1.5.7 and windows service to test uses .NET framework 1.1.

I have installed both 1.1 and 2.0 frameworks. I tried to compile the windows service with 2.0 framework but i got the same error.

It's running in a Win XP SP2.

Any idea?

Thanks, Luigi.
