CAUSE

When you install Crystal Reports version 8.0, default security permissions are changed on certain registry keys (for example, HKEY_CLASSES_ROOT\Interface and HKEY_CLASSES_ROOT\TypeLib).

When COM+ fails to access the registry keys because of insufficient permissions, the error messages described in the "Symptoms" section can occur.

RESOLUTION

To workaround this problem, reset the registry key permissions that are changed when you install Crystal Reports.
