Just something to consider... I, for 1, use a computer running Win 10 & this is what I did to set up SH3 to it:
When I went to install SH3, I avoided C:/Program Files & C:/Program Files (X86) completely & set up a folder as follows:
C:/Games/SH3/(whatever mod I decided to use here, for me, I used /LSH3-2015, since I went with it...)
Hope this helps you out...
