Location Of ActiveX Controls?

I use the Active X calendar control 10.0 in a number of forms*. The mscal.ocx file is in c:Program FilesMicrosoft OfficeOffice 10.

(*In the calendar's Properties it says it is "MSCAL.Calendar.7", which I think is just MS's way of confusing people.)

After splitting the deploying my app, it appears lots of my users either don't have version 10.0 or it is stored someplace else; for example, in C:WindowsSystem32. Because they don't have the correct version/path, everything crashes.

So, how can I easily determine whether users have the right ActiveX in the correct location?

The Microsoft web site says "To distribute your component as part of a Visual Basic application, you can use Package and Deployment Wizard". I don't have that wizard in my version of Access (2002 SP3 on Windows XP), so that's not an option.

Microsoft also says to "To enter the base address for your component, open the Project Properties dialog box and select the Compile tab. The address is entered in the DLL Base Address box, as an unsigned decimal or hexadecimal integer. The default value is &H11000000 (285,212,672). If you neglect to change this value, your component will conflict with every other in-process component compiled using the default. Staying well away from this address is recommended." It seems to make sense that I put the mscal.ocx in the database's directory on the server to serve as the "base address", but other than that this option scares the heck out of me.

Does someone have any suggestions how to easily ensure users have the right ActiveX version on their computer - and in the correct location? (I'm not a super-coder.)

As always, thanks
