Fails to install (requires Windows 3). The installer complains about setting properties. I know this is a fork of the original dosbox, but I believe this issue raised at Dosbox-X is likely to be the root cause of the problem. (If there is a comparable issue raised against the original Dosbox please swap the link for the one that refers to Dosbox).
There is an patch which makes it work on Windows XP at http://www.gspsupport.co.uk/index.php?page=support2/show_faq&faqID=1346&productID=2711
