Automation error

[vb_dba]

I have created a class that is used to send email. I use this in almost all of my applications and have never had a problem w/ it until last week. I am getting the following error message:

Error #430: Class does not support automation or does not support expected interface.

Can anyone give me an idea of what I'm doing wrong or what happened? The problem doesn't occur on all PC's, so it is really puzzling.

I'd appreciate any help.

Regards,

Chris

You are using the wrong versions DLL on some PC. For example if you are using ADO, check its version and make sure the PC with the problem have the same ADO version as the correct one.

Also, make sure that all OLE DLLs on the client machine has the same version or newer as the ones you compiled the DLL with.
