Since PDF-XChange is not your default viewer, I suggest that you create your shortcut with the command "Run AutoHotkey code" (by adapting one of the following two scripts):
Open a PDF document with PDF-XChange
Open a selected PDF document (in Windows File Explorer or on the desktop) with PDF-XChange
Open a PDF document with PDF-XChange
run % "C:\Program Files\Tracker Software\PDF Viewer\PDFXCview.exe ""C:\Path\FileName.pdf"""
Open a selected PDF document (in Windows File Explorer or on the desktop) with PDF-XChange
ClipSaved := ClipboardAll
Clipboard =
SendInput, ^c
ClipWait, 2
if ErrorLevel
{
MsgBox % "No file selected"
}
else
{
run % "C:\Program Files\Tracker Software\PDF Viewer\PDFXCview.exe """ Clipboard """"
}
Clipboard := ClipSaved
