If you've been having issues launching the BHD / C4 / JO Med (Or any other NovaLogic med) recently, Sil and I have found a fix for it.
Download the app below. This will install a set of compatibility flags for the mission editors to help them run properly under Windows 10 1703+. It will also allow you to install fixes for DF1, DFLW and DFTFD and other games.
Thanks to everyone for all the information that helped make this app possible.
