Yes it does. And yes, it is correct bahavior from WPKG point of view. The reason 
is that in case WPKG (WSH script) runs in 32-bit WSH interpreter, then it has no 
possibilities to access virtualized 64-bit file system or registry elements.

As a result WPKG running in 32-bit WSH environment can only work with 32-bit 
software. For example checking uninstall entries for 64-bit software is not 
possible when WPKG is running wrongly in 32-bit WSH environment.

Though you can still run 32-bit WPKG client if you manually run 
%SystemRoot%\sysnative\cscript.exe instead of 32-bit cscript.exe. But I strongly 
recommend to use 64-bit WPKG client directly.

Only when run in 64-bit WSH environment WPKG can work with all 64-bit system 
properties, and only in this setup it makes sense to detect the system as being 
a 64-bit system.
