Wrong/Missing Icons in IrfanView x86

[raywood]

In Windows 11 24H2, I have assigned IrfanView x86 to play audio (e.g., .wav) files, and I have assigned IrfanView x64 to display image (e.g., .png) files.

Those assignments function correctly. In this example, the DW*.wav files play in the x86 version, and the perfmon*.png files display in the x64 version.

For some reason, however, as shown in the accompanying image, the usual IrfanView icons are not displaying next to the .wav files. Instead, I get a dim checkmark icon. The same is true for .mp3 files.

My other icons (for e.g., .pdf, .mp4 files) are functioning normally.

I run Windows 10 and IrfanView 4.70 32bit and can confirm this issue has been happening for a least the last 3 version updates.
I have set the IV player to run my mp3 files, with several shortcuts set on the desktop - their icons change from the red cat to white tick mark when the version gets an update.

I fix the problem using the program FileTypesMan, selecting the default red cat icon for mp3 and all is well again.
The problem with the white tick icon, is that is is almost impossible to see against a white background, as show in @raywood's image above.

FileTypesMan shows these icons are hidden within IV, but the default icon get changed every time the software is updated.


Would be great if the default icon could be reset for future releases.
