Webetiser, which comes in a free version, "Worx", and various paid versions (including those for distribution via CD or other media), runs primarily on Windows NT. It has indexing and configuration wizards using a Windows GUI, and the paid versions read Word, Excel, PowerPoint and Acrobat PDF files (via OLE). It can index local file shares, and offers a reasonable set of templates for results presentation, using a set of JavaScript files. It's been around for a while as re.s@earch suite, and has some happy customers.
