PDF-XChange Viewer ActiveX SDK supports all Windows (32/64 bit) operating systems from Windows XP** and later.
Version 2.5: Microsoft/Citrix Terminal Server compatible*.
* Note: Though many users have virtualized some of our component products such as the PDF-XChange Viewer and PDF-Tools application using XenApp, we do not support this at this time. Particularly the printer drivers are not designed to work in a virtualized environment.
** Limitations to product support for Windows XP
To experience the best performance of our products on all Windows operating systems, the onus is on users to ensure that they have all the latest available Microsoft Windows Service Packs & Updates installed.
