Sheridan OCX problems...

I am using some Sheridan OCX controls in an application I am using and,
after installing on the target system, the app {*word*99}s out whenever a form is
visible with one of their controls.  I have included the files they say to
include and registered the proper DLL's using REGSVR32.EXE, but I still get
Floating Point Errors when the form attempts to draw.  When I install the
developer's toolkit on the client machine, the app works fine, so I'm
missing something, I just don't know what and Sheridan isn't much help if
you aren't using VB.  Any ideas?  Perhaps I'm using REGSVR32.EXE
incorrectly, does anyone have any experience with it?
