after upgrading from 2.89A to 2.90A I now have two installations of the program, according to the Details panel of the executables:
2.89A under C>Program Files> mp3tag &
2.90A under C>Program Files (X86)>mp3tag
I'm surprised this happened, and also surprised that, since it did, that the positions of the two executables aren't reversed, since it is a 64 bit OS.
Can I delete the older version?
