Hi Jimmy,
The Form Wizard package is configured so that if you copy the contents of the wwwroot folder in the package into the root of your web site everything will land where it needs to go. So if your site root is in a folder named mojoportal then copy the contents of the wwwroot folder from the From Wizard package into that folder. Note that I said the "contents" of the folder, not the folder itself.
You could touch your Web.config by downloading it and uploading it again or you could just recycle the app from your web control panel if it has a button to recycle. And actually this step you could probably skip because when the form wizard dlls land in the /bin folder IIS will recycle the app anyway, so it isn't really essential to manually recycle it.
After uploading all the files just visit yoursiteroot/Setup/Default.aspx so it can run the database scripts for Form Wizard.
Hope that helps,
Joe
