MPC-HC's format-specific icons are not used (only generic "321" icon)

[OddTheodora]

Hi,

I'm using MPC-HC 1.8.4:
https://github.com/clsid2/mpc-hc/releases

MPC-HC has format-specific icons, showing you different icons according to file type, such as "AVI" icons for .avi files. However, sometimes the settings don't do anything, and I keep seeing the generic "321" icon for any filetype associated with MPC-HC. The format-specific icons are all saved in mpciconlib.dll in the MPC-HC directory, and the file is there alright. I've already tried reassigning the filetypes, and re-saving the setting in MPC-HC's options "use format-specific icons" (or something like that), rebooting the computer, all to no avail.

Any ideas how to fix this? Thx
