As per subject above.

I did add the built in Captcha control from CMSFormControls.
But receiving error
[Error loading the WebPart 'MyCaptcha' of type 'MyCaptcha']
Unable to cast object of type 'ASP.cmsformcontrols_captcha_Captcha_Simple_aspx' to type 'CMS.PortalControls.CMSAbstractWebPart'.

I already tried the entire day.
Adding a field named as SecurityCode.

All wasn't working.

Do any guys out there know the issue?
or
If there another workaround?

Thank you

You can't cast captcha control to CMSAbstractWebPart because it is a FormEngineUserControl not a webpart.
Because you try to add a captcha control to a page I suppose you have a on-line form(formerly BizForm) on it. Then you have to add a new field to that form and select it's type as one of the captcha controls.
