Excel VBA "Additional Controls" not working

Hi Folks. I have stumbled across some useful looking additional controls in excel.

When you’re in userForm editing view, click tools > additional controls…

There seems to be things like
EnterpriseLogonControll Class 11.5
Crystal Enterprise Tree Control
BusinessObjects Enterprise Repository Explorer Control 11.5

All of these sound like something I could make use of however when I include any, I get the attached errors and when I try to close Excel I get the first error again.

Does anyone have these working? Do I have to include additional references to other libraries? If so, which ones.

EDIT: Also I should probably add that this is ocurring when I try to display the userform which the external control is on. e.g. UserForm1.Show
error1.PNG
error2.PNG
