1.4.3 - settings - integration - file association - add new ProgID

[user0]

XnViewMP 1.4.3 64bit
Windows11 (22H2), display resolution 3840x2160, win scaling 150%

Settings - Integration
ProgID keys for some formats (AVIF, JFIF, etc) are not created in registry when you click "Set file associations...".
Therefore, after association with XnViewMP, files of these types are not opened in the Viewer tab, only the Browser tab is opened.

Solution
for windows 10 and above

1. register app in the system
   • run XnViewMP with admin rights
   • press 'Set file associations...' (in Settings > Integration) to create ProgID keys in registry
   • add missing keys, eg JFIF
     update path to match your case

     Code: Select all

     Windows Registry Editor Version 5.00
     
     [HKEY_CLASSES_ROOT\XnViewMP.jfif]
     @="JFIF Bitmap file"
     
     [HKEY_CLASSES_ROOT\XnViewMP.jfif\DefaultIcon]
     @="D:\\PROG\\portable\\graphic\\XnViewMP\\FileIcons\\jpg.ico"
     
     [HKEY_CLASSES_ROOT\XnViewMP.jfif\shell\open\command]
     @="\"D:\\PROG\\portable\\graphic\\XnViewMP\\xnviewmp.exe\" \"%1\""
