I am attempting to install Equalizer APO on my PC, and I downloaded the most recent update of the installation wizard, and the installation apparently went well, without error. But when I attempted to open APO for modification of my output sound, I got an error message saying that a specific .dll came up missing, and the program failed to load completely, recommending reinstallation. I proceeded to reinstall, and came up with the same error. Until I receive feedback, I will continue to search for more recent/reliable versions than that which was found on SourceForge.net. But, if anyone can provide some enlightenment as to why this particular error might be occurring, I would very much appreciate it. Thank you.
