    DTSWizardError: CoCreateInstance -- Error in the DLL


    I am trying to use export feature of DTS wizard and get the following message:

    DTSWizardError: CoCreateInstance

    Error in the DLL

    My environment:
    >Windows 2000 professional Client
    >SQL server 7.0


    As per one suggestion did the following without any success:

    >Re-install SP2
    >Re-install IE 5.5
    >Re-Register DTSPkg.dll [Regsvr32 \mssql7\binn\dtspkg.dll]


    Can you please help me out to solve this! Your help would be much appreciated.

    Thanks
    Suresh

    Whew - toughie (of course, a lot of these DevX questions have been that
    way).

    OK, what you have there is a situation where Windows has tried to create and
    instance of class and hasn't been able to for some reason. My guess would be
    a versioning issue of some kind and not having the appropriate DLL that
    supports a specific interface ID (a GUID that often changes by component
    version)..

    More than likely, and uninstall of the SQL Server and reinstall would fix
    things, but it would be nice to see an easier answer. Honestly, I would have
    expected the reapplication of the service pack (assuming that was the most
    recent you had previously applied) to fix the problem. It's still possible
    that installing SP3 would since it would, more thank likely, update all the
    DLL's in question, but I can't promise that.

    Other than the uninstall and reinstall or an upgrade to SP3, I really am out
    of suggestions. One possible resource would be to use the
    Microsoft.public.sqlserver.dts newsgroup. Euan Garden and other MS staff
    monitor that one sometimes and may point you to an easier solution.
