Also, what version of Crystal Reports for Adagio do you have (8.5A or 8.5B) and what version of Windows do you have? The older version of Crystal Reports 8.5A is not compatible with Windows Vista or Windows 7, meaning Custom Reports will not appear on workstations with those version of Windows.

An upgrade to Crystal Reports 8.5B supports compatibility with these versions of Windows. Perhaps you don't have this upgrade installed, and putting it in will solve the problem.
