PDF-XChange Will not set as the default PDF Viewer/Reader in Windows
This is sometimes caused by installing updates to Adobe Reader or even some just installing other Software or Hardware which may come supplied with Adobe Reader to allow you to read that products User Manual, despite your setting PDF-XChange as the default PDF Viewer and even doing so via the Menu option Edit -> Preferences -> File Associations, Windows persists in using another Viewer/Reader as the default application for PDF files.
Open a command Prompt with Administrative privileges
(See your Windows 'Help' for more info on a command prompt Window)
Navigate to the PDF-XChange install folder (by default this should be as below unless you elected to change the installer defaults or have a 64 bit system). This is the folder that contains the executable PDFXCview.exe. Type:
cd "C:\Program Files\Tracker Software\PDF Viewer" including the quotation marks.
run this command: PDFXCview.exe /makeassoc:web=true
This should set the file associations in Windows as well as your web browsers.
Note you must have Administrative rights for this to correctly function!
