Try the solution in this thread as another user had a similar problem:

Read posts 18-22, and use the link in Post 19.
And just to clarify, the ocx error is for Doug's FAST version not Handifast. Handifast can be used as a stand-alone program and doesn't need to register anything with Windows. Doug made it easy for users to use both programs by creating an installer program and having the ability to launch Handifast from within FAST.
