I had the same experience as Tim, exactly... "First, the answer is that DOSBox and Fractint run fine under Windows 10. This is the same DOSBox I had been using under Windows 8.1 (DOSBox svn 0.74). I haven't yet installed the latest Win 10 DOSBox". It also installs in a Chromebook HOWEVER, there's a problem with that one. The Chromebook keyboard is missing a couple of keys used by Fractint. and the upper row of keys must be reset to Function keys. Head scratching helps. John W.
