The calendar control name is msacal70.ocx in VFP 5.0 You can find a refrence between controls and names in the help titled *ActiveX Controls Overview*

BTW: You need to place the .ocx in the *first* driectory of your distribution tree. If you have a dir structure of say aaa\bbb, and you place the ocx in bbb, then tell setup wiz to place the control in Windows\System, it will instead place it in Windows\System\bbb, then the registration of the control will fail. This is using the *new* VFP 5.0 setup wizard.
