Re: Invalid class string error

Go back to msdn and download the Component Checker. Follow the instructions
to have it check for problems with your MDAC installation.

Thanks, Bob and Mike. We think the MDAC is the issue; however, when we
download the MDAC and try to run it, it gives error about the machine
having the latest version already. Is there a way to force the MDAC
installation? Maybe a refresh of the DLLs will fix this.

Hi. We're getting this error from an ASP app on an XP Pro system,

Server object, ASP 0177 (0x800401F3)
Invalid class string
/working_dbase/mathlab.asp, line 158

It's blowing up on the line where we instantiate an ADODB object
(please see below). The code runs fine on various other machines but
bombs out on this box.
It sounds as if you need to install/upgrade MDAC on this machine.
