first, welcome to subsim.
second, you are posting this question in the wrong forum. s/b in SH4 forum: https://www.subsim.com/radioroom/forumdisplay.php?f=202
third, in what folder did you install? if it was the default folder, you will need to do it again because Win10 places restrictions on old programs (like SH4) when they are installed in the default location (C:\Program Files (x86)). Use a unique folder name such as C:\Ubisoft or a secondary hard drive: D:\Ubisoft.
lastly, for now, go to the forum referenced above and review the SH4 TUTORIAL thread. all kinds of useful information for the newbie.
