Basically "yes", Wolfcat. However, most folks who have trouble run afoul of either failing to empty their Save folder, or have Silent Hunter installed in a Windows "Program Files" directory (folder), which will not allow any modding. The game has to be in a folder you created yourself that is outside of the Program Files folders. I will mention again that there is a file "01_FotRSU_Support_TOC.bat" in the root of the mod, which will start the "01_FotRSU_TableOfContents.pdf", which has links to quite a few other pdf documents with help files.
