Good day!
A long time ago, I bought the "Gold Edition" disc of the fifth installment of "Heroes of Might and Magic". There were no problems; I successfully installed it, played it, and later deleted it, putting the disc away for a better time.
And now, today, when I try to install any of the versions (Original, Hammers of Fate, and Tribes of the East), this message appears, attached below.
After clicking the "OK" button, everything simply closes completely.
