Module Name:
|
||
|
|
|
||
|
|
SevenKingdoms.cpp
|
||
|
|
|
||
|
|
Abstract:
|
||
|
|
|
||
|
|
The problem is in the installer that ships with some versions: specifically
|
||
|
|
the double pack: i.e. Seven Kingdoms and another. This installer reads
|
||
|
|
win.ini and parses it for localization settings.
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
This is an app specific shim.
