I have had troubles finding the Sins of a Solar Empire(SoaSE) mod path in Vista.
I searched multiple google searches and couldn't find any resourses that actually helped.
Every post I have seen just says what the path is, not how to find it.
This is a small guide based on my experience of actually finding the correct directory and why it is so hard to find.
The mod path is in the "C:\user\{computer name}\AppData" series of directorys. This directory is hidden. As Vista is fairly different in it's method of handling hidden driectorys than the other versions of windows it can be a bit of nightmare trying to get access to this series of directorys.
The easiest way of getting access is to right click on the Windows "Start" button and select "Explore". This will bring up the "Start" buttons directory. This directory is apart or the "AppData" series of directorys, so from there you can backtrack your way to the "AppData" core directory and then on to the Mod directory.
To find the correct Mod path, start SoaSE, Select Options, and there should be a tab "Mods" ,select this, and there should be a button that says "Show Mod Path". Select this button so you know exactly where you have to put the mods in order to get them to work. NOTE - Entrenchment uses it's own Mod path. Mods for entrenchment must be placed there to get them to work.
