Usually the Decode Error! In Irfanview, it usually shows up when we try to open an image or photo in RAW format from any camera, be it Canon, Nikon, etc. This is not really an error itself, but it is due to the lack of the necessary plugins to open these formats or simply because the plugins you have installed are not updated to the latest version.

As we have mentioned, Irfanview is updated relatively frequently and also has several Plugins that allow you to increase the functions of the photo viewer. These Plugins must be installed and updated continuously since if they are not done, you may find yourself unable to open certain image or photo files.

Furthermore, it must be taken into account that another of the most frequent problems is usually the installation of plugins that do not match the installed version, that is, 32 or 64 bits. This is one of the most common failures when the error is displayed:

“Decode Error! Can’t load plugin: formats.DLL “! Please install or update plugins from irfanview homepage!”
