This forum is largely run by volunteers who are not equipped to resolve installation issues. Since you have paid for the product, you are entitled to access professional support services!
For all installation queries I suggest starting at the Installation and Setup page. Clicking through any of those pages will take you to a form where you can give more details of your problem and you will get contacted by install support services. For example Download, installation, and updates.
I am sorry that you are experiencing a nightmare! I hope we can turn it into a dream soon enough. I think that if you try the links above you will get the help you need.
