    Hi All,

    I am using SQL Server 2000. Everything was working fine till morning and suddenly getting error "Class not registered" on clicking create new package.

    Any way to come out from this !!!

    Is this the issue you are having

    If you get the error: 'DTS Wizard Error - CoCreateInstance Class not Registered' apply the latest service pack or add MAXDOP(1) to the query which will prevent the query being parallelised.

    This error happens with parallel queries only. It means that one thread of the query is waiting for a message packet from another. To work-around this, you should apply the latest service pack or add MAXDOP(1) to the query which will prevent the query being parallelised.

    I think you may have to re-install SQL Server client tools

    Have you applied the latest service pack on the client tools?

    I have tried,

    1. unregister/register msdasql.dll file

    2. uninstall/install client tool + applied service pack 2.7
    + service pack 2.8 gives me error ( "This setup does not support installing on this operatin system" ). I am using windows XP.

    I am surprised why its not working fine once i have uninstall/install client tool.

    Still getting this Annoying error "CLASS NOT REGISTERED.".
