Error when addon runs on client workstation

Hi,

I have a problem with my addon running on a client wokstation. The addon is created using UIAPI and DIAPI.

It works fine on the server, but gives the following error on a client workstation.

"Activex cannot create object"

What is suspect is that this error is comming when i try to do the following

Set oDIComp = New SAPbobsCOM.Company

although i am not sure at this point of time.

Anyone ever got a similar problem.

Thanks.

Satish.
