being a 32-bit app is the cause
wpkg.xml is stored in system32
sytem32 is not the same physical directory for 64 and 32 bit apps.

system32 is the home of 64 bit dlls for a 64 bit app
syswow64 is mapped to system32 for a 32 bit app and contains 32 bit dlls

something similar happens in the registry

We need a 64 bit app in order to be able to check all thinkable.
some parts of the sytem are hidden to a 32 bit app
only a 64 bit app can access everything.
