 The actual problem is, the outlook 98 setup is comparing the language 
 informations of the Shell32.dll and the setup file (outlwzd.exe). But 
 according to the bug scenario, the system is having English OS and Japanese 
 Locale. So, Shell32.dll have English language as its language. So, this 
 differs with the Language informaiton of Japanese Outlook setuip file.

 So, setup thorows an error that the Language of the outlook 98 going to be 
 installed differs with the system language.

 This stub function lie about the language information of the outlook setup 
 file. Though the setup file is Japanese as language informaiton, this shim 
 returns as if it is English.
