Can you use an OCX without registering it?

I have an Excel Spreadsheet that is using the MS Calendar Control 9.0 in a form. I just found out that my target audience has imaged computers and MSCAL.OCX was not installed as part of the image. The uses do not have local admin rights so they can’t register the OCX themselves. I am able to place the MSCAL.OCX in the Microsoft Office directory.

Is there a way to use the OCX programmatically even though it is not registered?

No. OCXs are ActiveX Controls and as such they must be registered on the local system. When a calling application references an ActiveX Control it does so using an application id. The application id is "registered" in the registry with the information about the location of the OCX file, version, and other information. As you can see, the model requires the OCX file to be registered.
