I have an app that a client has just installed on a Win 7 OS and is having problems. The relevant error stack:

8 Reptwiz.Error (..\stonefield\sfreports\sfreports.vct)
7 Reptwiz.Ocommondialogloader.Loadactivex (..\stonefield\sfcommon\sfactivex.vct)
6 Reptwiz.Ocommondialogloader.Init (..\stonefield\sfcommon\sfactivex.vct)

And the error is:

OLE error code 0x80040112: Class is not licensed for use

Can anyone point me in the right direction?

TIA,
Dick
