Hi Lynda,
My version is showing 2.10i-6 on the printer driver - I'm assuming that's the version for all DLL's and what-not as well. The driver works great, but you do have to pass it this 128 character key anytime you try to activate the printer. This also applies when automating the print from Word. You first activate the printer, feed it the license key and then guide word through the printing process.
This has been working with Word 2000 through 2003 - I'm have yet to test it with 2007. I have yet to find anything else that produces PDF's as quickly as the Amyuni product. In addition, the cdintf.document object is great for gluing multiple PDF's together in various ways. The document object allows me to combine PDF's collected from outside agencies with 30 page word documents and jam them all into a single PDF for e-mail, fax or printing (to those printers that take forever to spool up each job).
I love the product - too bad the company decided to lose the royalty free policy. I've complained, cajoled and whimpered via e-mail, but they're not hearing it. I've got my eye out for something to take it's place, but everything else feels like a compromise. I hate that feeling!
Good Luck!
