Hello

  Check that all the PCs have the same version of Mdac, and insure that the third Pc has Mdac installed

This error cann occurs because someone manually copied a DLL to the pc where the Visual Basic runtime library is not located.

Create a new setup program for your application and deploy it to distribute ALL dependent DLLs.

Good Luck.
Try using Install Shield. MS Deployment Wiz, sucks.

You did not specify where the error occured.
We got it for instance on a ADO command object (on 3 out of 1500 PC's)

Till now we have not been able to find the offending program that destructs the registry or MDAC DLL's or  something like that.
Our only solution was to reinstall the PC (incl OS)
