Application not working when distributed

Hi,

We have incorporated Chilkat Zip into our VBA/MS Access application. It works fine on the development PC; the deployment package includes ChilkatZip.dll, and the dll appears to register correctly on the target system (in SysWow64).

Then, when attempting to create the zip object, the application raises the error "ActiveX component can't create object."

I've tried installing on two different target machines (other than the development machine) with the same results in both cases.

Any ideas what this could be?

Thanks, Alex
