Dear Fabio,

MSMAPI32.ocx is only a 'wrapper' for MAPI. You have to install MAPI before installing MSMAPI32.ocx.

But, once MSMAPI32.ocx is registered ether by regsvr32.exe or programatically, you only get this error, if you want to use this ocx by createobject() or addobject(). These commands requires the client machine to have the design time licence. (MS doesnot give you the right to distribute the design time licence to your clients.) How to avoid this?
Add this control to any of your form at desing time and instantiate that form.
And then use the MAPI control in your program.

That's all.
