>Hi,
>I am looking into using Code Co-op as Source Control software. According to the documentation it is compatible with Microsoft SSC, but it does not whow up in tools->options->ActiveSourceControlProvider. Any idea?

Try to uninstall it and install again. I just downloaded and installed it on PC with Win2kProSp3 and it shows up under tools -> options -> ActiveSourceControlProvider in VFP6 and VFP7.
