Module Name:
IgnoreOemToChar.cpp
Abstract:
Written originally to fix an Install Shield bug.
It may be specific to _ins5576._mp versions.
The executable _ins5576._mp calls OemToChar on the string
"%userprofile%\local settings\temp\_istmp11.dir\_ins5576._mp".
The call is unessasary and causes problems with path names that
contain non-ansi characters.
Notes:
This is a general purpose shim.
