What causes Code Base error 70 or 90?
These are usually temporary errors that can be resolved by restarting Windows. These errors may also be caused by using a logon that has insufficient permissions, or control, to the folder where CritiCall is installed. The logon used by the CritiCall administrator or test candidates must have complete permissions or Full Control to the CritiCall folder. If you do not know how to check or modify rights for the logon, see your system administrator.
