SCCM issue - "LANG_LIST has some locales which does not match with the locale of serial number"

I have a problem with the error "LANG_LIST has some locales which does not match with the locale of serial number" recurring.

I am trying to install Acrobat XI Std silently by SCCM.

I've used the Adobe Customisation Wizard to create a mst which include the volume serial number we have with our licence purchases. Note that I am in Australia. I use the command line in SCCM for the install as "msiexec /i "AcroStan.msi" TRANSFORMS="D&B_AcroStd.mst" /qn" which fails silently. If I install on a local machine using an admin command prompt and changing to /qb at the end, I get the aforementioned error.

I have a few things to try and resolve, having searched the adobe forums and other forums for the solution. The mst is only trying to install US English & I have even gone so far as to use the direct editor in the customisation wizard and change some values in the property table to resolve this. In the property table I can confirm that LANG_SEL_DEFAULT = ENU, REGIONAL_LIST = ENU, LANG_LIST = en_US, ProductLanguage = 1033

Is there a way to check the language specified for ym serial number?
