I have some guys that are running a debugger through query analyzer. They are getting the following error

Server: Msg 516, Level 16, State 1, Procedure sp_sdidebug, Line 1

[Microsoft][ODBC SQL Server Driver][SQL Server]Attempt to initialize OLE library failed. Check for correct versions of OLE DLLs on this machine.

I cannot seem to find to much out on google or Microsoft so I am hoping someone can shed some light.

Thanks Much
