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.
