Like I sad before I am just a player (I don't understand what is what in modding ) I still use win 7 (my hardware easily support win10) but I play Diablo 2 mods and Baldur's Gate mods so I feel more comfortable with win 7.
Regarding the difficulties you encounter I don't know what advice to give Maybe the community of moders is able to help you (@Necrolis seems to follow your work and give advises). From my side all I can do is to wish luck and patience sorry is little .... but when your mod will be releasable I will play with great pleasure
