The primary forms elements are contained in FM20.DLL. Set a reference to Microsoft Forms 2.0 Object library.
Occasionally some users have reported FM20.DLL missing or unregistered ( in which case you will not be able to set the reference).
If your PC is 64 bit (as most recent models are) then that file should be in the folder C:\Windows\SysWOW64, though it may be in C:\Windows\System32 in which case copy it to the other folder. You will then need to register it as described above (though you should register it as administrator).
Date pickers are a problem as invariable the OCX file will be unregistered and it must be registered on every PC. It will not work with the 64 bit versions of Office. I would therefore recommened using a VBA picker. I personally like Trevor Eyre's version which you can download from
