Iīve seen a lot of people have some problems by correctly launching the mod.
So iīve written a modfolder-upgrade to make your life easier.
How to setup and use it:
1) First download and unzip the file: IS.zip
2) Then put the folder "IS" from this file with itīs content into your data folder.
It is by default located in win64 here: C:\Program Files (x86)\Steam\SteamApps\common\empire total war\data
Or in Win32 here: C:\Program Files\Steam\SteamApps\common\empire total war\data
3) Now put all IS files into this folder, it should look then like this:
(Note that the Imperial Splendour folder should stay in data/campaigns.)
In the end the full installation inclusive the Easy IS load/unload upgrade should look like this:
You have not to edit the user_script in the appdata like in the original install instruction.
Just do all steps like i told you above, thats all.
Now you can start the mod by simple doubleclick on IS_load. The files will manage all for you. (loading the packfiles into the data folder, editing the user_script, starting empire)
If you are finished with playing and closed ETW doubleclick on IS_unload and all files and the user_script are cleared out.
This way you can easy put in, put out the mod.
