Unresolved COM References Encountered in Upgrade
The Upgrade Wizard has detected references to COM components in your project that could not be resolved. For more information, see the issue details in the upgrade report, for this category.
One of the reasons may be that the referenced COM component is not available on the system where the upgrade is being done. To rectify this, make sure that the project in Visual J++ 6.0 can be built and run on the same system where you are upgrading it to Visual J#.
