The only way to install this software is with the msi 32bit installer. Any other installer will just freeze and not display anything. If you selected OTHER under the list of applications, everything should go normally and finish the installation without any problems. In the case you selected the PDF-Xchange Viewer 2.x tie as a based and installed PDF Xchange Editor there, you will see an error at the end that you can skip.
On the installation dialog, make sure you select Custom installation instead of Complete. In the next window, make sure that "Tracker Update" is NOT selected. If you proceed to install the updater, PDF Xchange Editor will open but soon after it will freeze and crash showing you and error log.
