  2. Check if Foxit PDF Editor is installed
    Look for Foxit PDF Editor in the Windows registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall, or check for the executable at C:\Program Files\Foxit\Foxit PDF Editor.exe or in similar Program Files directories
    Affected if Foxit PDF Editor is found on the system
  3. Determine the installed version of Foxit PDF Reader
    Right-click on FoxitReader.exe and select Properties > Details to view the File Version, or query the registry key HKLM\SOFTWARE\Foxit Software\Foxit PDF Reader for the Version value
