Saving Office 2007 documents as PDF

Finally Office 2007 allows you to save office documents as PDF files. During beta stages this support was supposed to be "native". However, the released version requires you to download an add-on for the same. The add-on is a FREE download but before downloading it checks if you have genuine version of the software. That means you must download it from the same maching on which you have Office 2007 installed. I know many small companies where internet connection is not available on each and every maching. Moreover, the resultant PDF files are not much attractive. Previously I used PDF Creator but for some reason it is crashing under Windows Vista.
