For me, when running the program, it comes up with a windows saying it's installing office proffesional 2010 (which I do have installed) then opens the MP3Gain program normally.
I accidentally clicked it a few times when pressing the minimize button, which is my own error but annoying since it opens a browser window. It doesn't actually obstruct anything. I guess as a reccomendation, I'd put it below language selection instead.
Can an option be added to remove the new referral link now present at the top of the interface in the newest version?
