could be a bug, i'm runing wpi from svcpack using ryanvm's integrator wpi plugin, when wpi launches it complains that about 'OSLanguage' being null or not an object.
it seems to trace to Enum = sLang.OSLanguage; in core.js

if i recall correctly i also saw a different error message once for the same problem with less information but i still traced it to Enum = sLang.OSLanguage; in core.js

could be it happens because regional options settings are skipped (i'm providing them in winnt.sif), still it should pick a default not throw an error.
this happens when installing from a cd of windows xp sp3 vl english source on vmware.



lots of hugs thank you for all the great work

It must be something to do with the service pack because it should have a language set no matter what. WPI may be running before the language is set; I don't know for sure.

I put some better code and a default to English so hopefully no more error message from the above situation.

thank you
