Hi Steven
Unfortunately, almost all of us here already have the product
successfully installed.
First, I'd try what is outlined in
this link.. If that
doesn't help, I'd strongly encourage you to contact Adobe support
and see what they have to say.
For what it's worth here, Adobe has changed the installation
method for most of their products. This means that installation
issues aren't problematic with only Captivate. There are issues
with many of the products.
Cheers... Rick
