In order to confirm that the ActiveX control is in fact working on your machine, did you test the sample AutoVue Desktop Deployment ActiveX application that ships with the product? (Start > Programs > Oracle AutoVue Desktop Deployment > Examples > Sample ActiveX Application).
If the sample is working, did you double-check the various online discussions of this particular error ("") in MS Access context, e.g.:
- etc. (many more references through Google search)
Alternatively, if your users have a web-based interface to MS Access (e.g. Sharepoint, ASPdatabase.net, custom ASP, etc), then you may want to instead consider the "Client/Server Deployment" of AutoVue and embed AutoVue as an applet, rather than using the ActiveX component from the "Desktop Deployment" of AutoVue. This could also be a benefit in terms of administrative overhead, if your dozens of users are located within the same LAN.
