Any PDF viewer which includes with a Preview Handler should work in Opus. e.g. Adobe Reader or PDF-XChange.

(Note: Adobe Acrobat does not come with a PDF preview handler. You must install Reader to get the viewer components if you want to use Adobe's viewers.)

You can also use PDF ActiveX controls and PDF plugins for Internet Explorer, although it requires an extra configuration step, and preview handlers are generally recommended.
